Custom Images (via Google Drive)

The Gamma API doesn't have a dedicated image upload endpoint. To use your own images (AI-generated, diagrams, screenshots):

Generate or obtain your image (e.g., via nano-banana-pro skill)

Upload to Google Drive using the google-docs-skill:

python3 ~/.claude/skills/google-docs-skill/docs_skill.py upload-image /path/to/image.png

Use the directUrl (lh3.googleusercontent.com format) in your inputText:
```
Use this image: https://lh3.googleusercontent.com/d/FILE_ID
```
Set --image-source noImages so Gamma uses only your provided URLs

Important: Only lh3.googleusercontent.com/d/{id} URLs work. The drive.google.com/uc?export=view format does a 303 redirect that Gamma cannot follow.

Full Pipeline Example

# 1. Generate image
python3 ~/.claude/skills/nano-banana-pro/generate_image.py "circuit board closeup" --output /tmp/imgs

# 2. Upload to Drive (returns lh3 direct URL)
python3 ~/.claude/skills/google-docs-skill/docs_skill.py upload-image /tmp/imgs/image.png

# 3. Embed URL in content and generate deck
python3 ~/.claude/skills/gamma-skill/gamma_skill.py generate \
  "Title slide. Use this image: https://lh3.googleusercontent.com/d/FILE_ID ..." \
  --image-source noImages --wait

Credit System

Gamma uses credits for generation:

Slides: 3-4 credits each
AI Images: 2-120 credits depending on model
Pro: ~400 credits/month
Ultra: ~1000 credits/month

Use --image-source pexels or --no-images to conserve credits.
