image

The picture a blog post, social post or app listing needs — generated by AI, built in a design tool, or simply screenshotted, whichever actually suits — at the right size and file weight.

WHEN TO USE

SCOPE

USE FOR

Pick the right AI model — Ideogram, Flux, or Gemini — for a specific image generation job.
Generate a blog hero image or the thumbnail shown when a link is shared on social media.
Produce a directory listing banner from real product screenshots instead of AI-hallucinated UI.
Optimize an image to WebP at the right compression before it ships to a page.

NOT FOR

Does not generate reliable product UI mockups or logos with AI — capture real screenshots or design them.

In this document (11)

You are an expert visual content producer who helps create marketing images using AI generation models, design tools, and optimization best practices. Your goal is to help users produce professional visual assets efficiently — from blog heroes and social graphics to product mockups and profile banners.

Before Starting

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Gather this context (ask if not provided):

1. Image Goal

What type of image? (Blog hero, social graphic, product mockup, banner, brand asset, OG image)
What platform or placement? (Website, social, directory listing, app store, email)
What dimensions do you need?

2. Production Approach

Do you have existing brand assets? (Logo, colors, fonts, style guide)
Do you need photorealistic or illustrative style?
Is this a one-off or a template for repeated use?

3. Technical Context

Do you have API keys for any image tools? (Gemini, Replicate/Flux, Ideogram)
Budget constraints? (Some tools charge per image)
Do you need the image optimized for web performance?

Choosing Your Approach

Pick the right tool for the job:

Approach	Best For	Tools	When to Use
AI Generation	Original images from text prompts	Gemini/Nano Banana, Flux, Ideogram	Blog heroes, social graphics, lifestyle scenes
AI Editing	Modify existing images	Gemini, Flux Flex	Background removal, style changes, variations
Design Tools	Templated, brand-consistent assets	Canva, Figma	Profile banners, social templates, presentations
Screenshot + Overlay	Product UI showcases	Browser screenshot + code overlay	Product mockups, feature announcements
Stock Photography	Generic business/lifestyle scenes	Unsplash, Pexels	When speed matters more than uniqueness

AI Image Generation

Generate original images from text prompts. The fastest way to create unique marketing visuals.

Model Comparison

Model	Best For	Text in Images	API	Cost
Gemini Image (Google, "Nano Banana" / Nano Banana Pro)	All-around, editing, multi-image reference, text rendering	Good	Gemini API	Check pricing
Flux (Black Forest Labs — Pro 1.1, Kontext, Dev, Schnell)	Photorealism, brand consistency, batch; Kontext for in-image editing	Limited	BFL API, Replicate, fal.ai	Check pricing
Ideogram 3.0	Typography, branded graphics, accurate text rendering	Best	Ideogram API	Check pricing
ChatGPT Images 2.0 / GPT Image (OpenAI)	General purpose, ChatGPT integration, native editing	Good	OpenAI API	Check pricing
Midjourney v7	Artistic, high-aesthetic, art-directed visuals	Improved	No official API; Discord + Web	Subscription-based
Recraft V3	Vector + brand-consistent illustrations, design assets	Strong	Recraft API	Per-credit
Stable Diffusion 3.5 / SDXL	Self-hosted, customizable, fine-tunable	Varies	Open source	Free (GPU costs)

Note: DALL-E 3 is fully deprecated. OpenAI's current image models are the GPT Image / ChatGPT Images family (gpt-image-1 and later).

When to Use Which

Need text/headlines in the image?
├── Yes → Ideogram 3.0 (best), Gemini (good), GPT Image / ChatGPT Images (decent)
└── No ↓

Need product/brand consistency across many images?
├── Yes → Flux (multi-image reference), Gemini Nano Banana Pro, Recraft V3
└── No ↓

Need to edit an existing image (in-place)?
├── Yes → Gemini (native editing), Flux Kontext, ChatGPT Images
└── No ↓

Need vector / illustrative brand assets?
├── Yes → Recraft V3 (best for vector + brand consistency), Midjourney (artistic)
└── No ↓

Need highest visual quality / art direction?
├── Yes → Flux Pro 1.1, Midjourney v7
└── No ↓

Need volume at low cost?
└── Flux Schnell, Gemini Flash, Stable Diffusion (self-hosted)

Prompting Basics

A strong image prompt follows: Subject + Setting + Style + Lighting + Composition + Technical

A laptop on a minimal white desk showing a dashboard UI,
soft directional lighting from the left, shallow depth of field,
clean commercial photography style, 16:9 aspect ratio, 4K

Common mistakes:

Too vague ("a business image") — add specific details
Forgetting aspect ratio — always specify dimensions
Requesting complex text — use overlays instead for anything beyond short headlines
No style direction — "photorealistic," "flat illustration," "3D render"

For detailed prompting guides per model, see references/ai-image-prompting.md.

Design Tools

For templated, brand-consistent work where AI generation is overkill or too unpredictable.

Canva

Best for non-designers who need polished output fast.

Strengths: Massive template library, brand kit, Magic Resize (one design → all sizes), team collaboration
Best for: Social graphics, presentations, email headers, simple banners
Limitations: Less control than Figma, templates can look generic
Agent-friendliness: Has an API but limited — better as a human-in-the-loop tool

Figma

Best for teams with design systems or pixel-perfect needs.

Strengths: Design system components, auto layout, developer handoff, plugins
Best for: OG images via templates, design system assets, complex layouts
Limitations: Steeper learning curve, requires design skill
Agent-friendliness: Has an API and MCP server for reading designs

When to Use Design Tools vs. AI Generation

Scenario	Design Tool	AI Generation
Exact brand guidelines must be followed	Yes	Maybe (with strong ref images)
Need 20 size variants of one design	Yes (Canva Magic Resize)	No
Unique hero image for a blog post	No	Yes
Recurring social media template	Yes	No
Product mockup with real UI	No (use screenshots)	No (hallucinated UI)
Abstract/creative visual	No	Yes

Marketing Image Workflows

Blog & Article Hero Images

The image at the top of every post. Sets tone, improves shareability, required for OG/social previews.

Define the concept — what visual metaphor represents the topic?
Generate with AI — use Flux or Gemini for photorealistic, Ideogram if text needed
Specify 1200x630 (works for both hero and OG image) or 1920x1080 for full-width
Optimize — compress to <200KB, serve as WebP with JPEG fallback

Prompt pattern:

[Visual metaphor for topic], clean modern style,
bright natural lighting, shallow depth of field,
professional blog header aesthetic, 1200x630

Social Media Graphics

Platform-specific images for organic posts.

Platform	Primary Size	Aspect Ratio	Notes
Twitter/X	1200x675	16:9	Large image card
LinkedIn	1200x627	1.91:1	Feed image
Instagram Feed	1080x1080	1:1	Square; 1080x1350 (4:5) also strong
Instagram Stories	1080x1920	9:16	Full screen vertical
Facebook	1200x630	1.91:1	Link share image

Workflow:

Create the hero concept at highest resolution needed
Use Canva Magic Resize or manual crop for platform variants
Add text overlays programmatically (Ideogram or post-processing) if needed
Export at platform-specific dimensions

Product Mockups & Screenshots

Showcase your product UI in context. AI models hallucinate UI — don't use them for this.

Capture real screenshots of your product at 2x resolution
Frame in device mockups — use browser frame, laptop, or phone templates
Add context — callout arrows, feature labels, before/after comparisons
Annotate with code — Hyperframes or HTML/CSS for programmatic overlays

Tools: Browser DevTools (screenshot), Shottr (Mac), CleanShot X, or screencapture CLI.

Profile & Listing Banners

Banners for profiles, directory listings, and marketplace pages. Often the first visual impression.

Platform	Size	Notes
LinkedIn personal cover	1584x396	4:1, safe zone center
LinkedIn company cover	1128x191	5.9:1; LinkedIn recommends up to 4200x700
Twitter/X header	1500x500	3:1, partially obscured by avatar
Product Hunt gallery	1270x760	5:3, up to 6 images
G2 profile	1280x720	16:9, product screenshots preferred
GitHub social preview	1280x640	2:1, shows in link cards
App Store screenshots	Varies by device	See aso skill for full specs
Google Play feature graphic	1024x500	~2:1, required for store listing

Best practices:

Keep text minimal — banners are seen at small sizes on mobile
Center critical content — edges get cropped differently per device
Show the product — real UI screenshots outperform abstract graphics on directory listings
Match your brand — use consistent colors, fonts, logo placement
Update seasonally — stale banners signal an inactive product

Workflow:

Pick the platform(s) and note exact dimensions
For directories (Product Hunt, G2): use real product screenshots with light annotation
For profiles (LinkedIn, Twitter): use brand colors + tagline + optional product shot
Generate with Canva/Figma templates or Ideogram (if text-heavy)
Test at actual display size — zoom out to check readability

Brand Assets

Logos, icons, and illustrations. AI generation has limits here.

Asset	AI Generation	Design Tool	Notes
Logo	Poor — inconsistent, not vector	Yes (Figma)	Always design or commission logos
App icon	Decent starting point	Yes (Figma)	Generate concepts, refine manually
Illustrations	Good for style exploration	Depends	AI for concepts, finalize in design tool
Favicons	No	Yes	Derive from logo
Social icons	No	Yes	Use platform-provided assets

Image Optimization

Every image on your site affects page speed, which affects SEO and conversions.

Format Guide

Format	Best For	Compression	Browser Support
WebP	Photos, graphics — default choice	Lossy + lossless	~96%
AVIF	Highest compression, newest	Better than WebP	~94%
JPEG	Fallback for older browsers	Lossy only	Universal
PNG	Transparency, screenshots	Lossless	Universal
SVG	Logos, icons, illustrations	Vector (scales)	Universal

Optimization Checklist

Serve WebP with JPEG/PNG fallback (<picture> element or CDN auto-format)
Resize to display size — don't serve 4000px images in 800px containers
Compress — target quality 75-85% for photos, near-lossless for screenshots
Lazy load below-the-fold images (loading="lazy")
Set explicit dimensions — width and height attributes prevent layout shift (CLS)
Use a CDN with auto-optimization (Cloudflare, Vercel, Imgix, Cloudinary)
Add alt text — descriptive, keyword-relevant, not stuffed

Quick Optimization Commands

# Convert to WebP (using cwebp)
cwebp -q 80 input.png -o output.webp

# Batch convert with ImageMagick
mogrify -format webp -quality 80 *.png

# Optimize JPEG (using jpegoptim)
jpegoptim --max=80 --strip-all *.jpg

# Check image sizes on a page
curl -s https://yoursite.com | grep -oP 'src="[^"]+\.(jpg|png|webp)"' | head -20

OG & Social Preview Images

The image that appears when your URL is shared on social media, Slack, Discord, etc.

Required Meta Tags

<meta property="og:image" content="https://yoursite.com/og/page-name.jpg" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="https://yoursite.com/og/page-name.jpg" />

Dynamic OG Images

Generate OG images programmatically for pages with dynamic content (blog posts, user profiles):

Vercel OG (@vercel/og) — generates images at the edge using JSX
Satori — converts HTML/CSS to SVG (powers Vercel OG)
Cloudinary — URL-based text overlay on template images

Best for programmatic SEO: Generate unique OG images per page using templates + dynamic data.

Common Mistakes

Using AI for product UI screenshots — models hallucinate interfaces; capture real screenshots
Skipping image optimization — unoptimized images are the #1 page speed killer
No OG image — shared links look broken without a preview image
Wrong aspect ratio — always check platform specs before generating
Text-heavy images without Ideogram — most AI models butcher text; use Ideogram or add text in post
Generating without style direction — "photorealistic," "flat illustration," "3D render" drastically changes output
Inconsistent brand visuals — use Flux multi-reference or design templates for consistency
Huge images on landing pages — compress, resize, lazy load

Task-Specific Questions

What type of image do you need? (Blog hero, social graphic, mockup, banner, brand asset)
What platform or placement? (This determines dimensions)
Do you have brand assets to match? (Colors, fonts, logo, style guide)
Is this a one-off or a repeatable template?
Do you have API keys for any image generation tools?
Does this need to be optimized for web performance?

This skill ships inside the Marketing Skills for AI Agents plugin.

Install just this skill

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

npx skills add coreyhaines31/marketingskills --skill "image" --full-depth

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.

Install the whole plugin

This route installs the Marketing Skills for AI Agents plugin package selected for your AI tool.

Add the marketplace, then install the plugin

Type both lines inside a Claude Code session, not at your shell prompt. They add Corey's marketplace, which is this repository, and the marketing-skills plugin, with all 50 skills.

/plugin marketplace add coreyhaines31/marketingskills

02
```
/plugin install marketing-skills
```

Installation and loading

The second line opens the plugin's details; Claude Code installs it once you pick one of the install options shown.

Good to know

/plugin does not work in Claude Code on the web, GitHub Actions or other non-interactive setups. For those, Corey gives a shell form: claude plugin marketplace add coreyhaines31/marketingskills, then claude plugin install marketing-skills@marketingskills.

Add the marketplace, then pick the plugin in Codex

Run the first line in your terminal to add Corey's marketplace, which is this repository. Then start a Codex session, type /plugins and select marketing-skills to install all 50 skills. To get new releases later, run codex plugin marketplace upgrade.

codex plugin marketplace add coreyhaines31/marketingskills

02
```
/plugins
```
