Image Fetcher

Image Fetcher

Fetch relevant, free-to-use images from the web for any project context.

Config

Read config from ~/.claude/skills/image-fetcher/config.json:

{
  "unsplash_key": "",
  "pexels_key": "",
  "pixabay_key": "",
  "default_count": 5,
  "output_dir": "assets/images"
}

All fields are optional. The skill works with zero configuration via the WebSearch fallback.

Load config silently at the start of every invocation:

cat ~/.claude/skills/image-fetcher/config.json 2>/dev/null || echo '{}'

Phase 1: Determine What to Search For

If the user provided input (argument after the skill name), use that directly as the search context. Skip to Phase 2.

If no input was provided, scan the current directory for context signals:

Use Glob and Read to scan. Build a brief internal context summary:

CONTEXT:
  project: [name or "unknown"]
  domain: [web app / game / docs / CLI / etc.]
  keywords: [extracted keywords]
  existing_images: [list of what's already there]

If the directory scan yields nothing useful (empty dir, no descriptive files), use AskUserQuestion:

"What kind of images are you looking for?"
Options:
- Hero/banner images
- Product photos
- Abstract/background textures
- Icons/illustrations
- Other (describe)

Then ask a follow-up for specifics: subject, mood, color preference.

From the context, generate 1-3 concise search queries (e.g., "minimalist coffee shop interior", "abstract tech gradient background").

Present the queries to the user:

Based on your project context, I'll search for:

1. "minimalist coffee shop interior"
2. "coffee beans close-up warm tones"
3. "cozy cafe atmosphere"

Want me to adjust any of these?

Proceed when the user confirms (or adjust if they give feedback).

Phase 2: Fetch Images

Use the first available source from this priority chain:

Source 1: Unsplash API (if unsplash_key is set and non-empty)

curl -s "https://api.unsplash.com/search/photos?query=QUERY&per_page=COUNT&orientation=landscape" \
  -H "Authorization: Client-ID UNSPLASH_KEY"

Extract from JSON response:

• results[].urls.regular — download URL (good quality, ~1080px wide)
• results[].alt_description — image description
• results[].width, results[].height — dimensions
• results[].user.name — photographer name
• results[].links.html — source page URL

Source 2: Pexels API (if pexels_key is set and non-empty)

curl -s "https://api.pexels.com/v1/search?query=QUERY&per_page=COUNT&orientation=landscape" \
  -H "Authorization: PEXELS_KEY"

Extract from JSON response:

• results[].src.large — download URL
• results[].alt — image description
• results[].width, results[].height — dimensions
• results[].photographer — photographer name
• results[].url — source page URL

Source 3: Pixabay API (if pixabay_key is set and non-empty)

curl -s "https://pixabay.com/api/?key=PIXABAY_KEY&q=QUERY&per_page=COUNT&image_type=photo&orientation=horizontal"

Extract from JSON response:

• hits[].largeImageURL — download URL
• hits[].tags — image description
• hits[].imageWidth, hits[].imageHeight — dimensions
• hits[].user — photographer name
• hits[].pageURL — source page URL

Source 4: WebSearch Fallback (zero config, always available)

If no API keys are configured, use WebSearch:

WebSearch: "free stock photo {QUERY} site:unsplash.com OR site:pexels.com OR site:pixabay.com"

From the search results, extract individual photo page URLs (e.g., pexels.com/photo/TITLE-ID/).

Important: Stock sites block WebFetch scraping (return 403). Do NOT attempt to WebFetch individual photo pages. Instead, use known CDN URL patterns to construct direct download URLs:

Pexels CDN Pattern

Extract the numeric photo ID from the Pexels URL (e.g., 417074 from /photo/lake-and-mountain-417074/), then construct:

https://images.pexels.com/photos/{ID}/pexels-photo-{ID}.jpeg?auto=compress&cs=tinysrgb&w=1920

Unsplash CDN Pattern

Extract the photo slug from the Unsplash URL (e.g., abc123 from /photos/abc123), then construct:

https://images.unsplash.com/photo-{SLUG}?w=1920&q=80

Note: Unsplash slugs can be complex. If the direct CDN URL doesn't work, search for individual photo pages on Pexels instead — their CDN pattern is more reliable.

Pixabay

Pixabay CDN URLs are not predictable without the API. If only Pixabay results are found, suggest the user configure a free API key.

If no individual photo URLs are found, try a second search:

WebSearch: "pexels free stock photo {QUERY}"

Collect up to default_count (default 5) image candidates from whatever source was used.

Phase 3: Present Candidates

Present the fetched images to the user in a clear table:

Found 5 images for "minimalist coffee shop interior":

| # | Description | Size | Source | Photographer |
|---|-------------|------|--------|-------------|
| 1 | Cozy cafe with wooden tables and warm lighting | 1920x1280 | Unsplash | John Doe |
| 2 | Modern coffee bar with espresso machine | 1800x1200 | Unsplash | Jane Smith |
| 3 | Minimalist white cafe interior | 2000x1333 | Unsplash | Alex Chen |
| 4 | Coffee shop window seat with natural light | 1920x1080 | Unsplash | Maria Garcia |
| 5 | Rustic coffee house with brick walls | 1600x1067 | Unsplash | Sam Wilson |

Then ask:

AskUserQuestion: "Which images would you like to download?"
Options:
- All of them
- Pick specific ones (enter numbers like 1, 3, 5)
- None — search again with different terms

Phase 4: Download & Save

For each selected image:

1. Create the output directory if it doesn't exist:

mkdir -p ./OUTPUT_DIR

2. Generate a descriptive filename from the image description:

   • Lowercase, hyphenated, max 50 chars
   • Append a number suffix if needed to avoid collisions
   • Keep the original file extension (.jpg, .png, .webp)
   • Example: cozy-cafe-warm-lighting-01.jpg

3. Download with curl:

curl -sL "IMAGE_URL" -o "./OUTPUT_DIR/FILENAME"

4. Verify the download:

file "./OUTPUT_DIR/FILENAME"

Confirm it's a valid image file (not an HTML error page).

5. If the download fails or produces an invalid file, skip it and note the failure.

Phase 5: Summary

Print a final summary:

Downloaded 3 images to ./assets/images/:

  1. assets/images/cozy-cafe-warm-lighting-01.jpg (1920x1280, 245 KB)
     Source: unsplash.com/photos/abc123 | Photo by John Doe
  2. assets/images/modern-coffee-bar-02.jpg (1800x1200, 198 KB)
     Source: unsplash.com/photos/def456 | Photo by Jane Smith
  3. assets/images/minimalist-white-cafe-03.jpg (2000x1333, 312 KB)

Error Handling

• No API keys and WebSearch returns no usable results: Tell the user to configure at least one API key in ~/.claude/skills/image-fetcher/config.json for better results. Offer to help them get a free key (link to signup pages).
• API rate limit hit: Fall back to the next source in the chain.
• Download fails: Skip the image, note it in the summary, continue with others.
• All downloads fail: Report the issue, suggest trying different search terms.
