github-images

Download image attachments from GitHub issues and pull requests, including private repos that require authentication.

When to use

  • User shares a GitHub issue/PR URL and you need to view screenshots or images from it
  • You need to download image attachments from a private repo
  • User asks to "grab the screenshots from that issue" or similar

Usage

bash
# From a full GitHub URL
ghimg https://github.com/owner/repo/issues/39

# From a PR URL
ghimg https://github.com/owner/repo/pull/42

# Using owner/repo and number separately
ghimg owner/repo 39

# Custom output directory
ghimg owner/repo 39 -o ./screenshots

# Print signed URLs only (pipe-friendly)
ghimg owner/repo 39 --urls-only
Default output: 
/tmp/ghimg/<owner>/<repo>/<number>/
After downloading, use 
Read
to view the images (Claude Code supports image files).

Manual fallback

If 
ghimg
is unavailable, use 
gh api
directly:
bash
# Fetch body_html with signed image URLs (valid ~5 min)
gh api repos/owner/repo/issues/39 \
  -H "Accept: application/vnd.github.full+json" \
  --jq '.body_html'

# Fetch comment images too
gh api repos/owner/repo/issues/39/comments \
  -H "Accept: application/vnd.github.full+json" \
  --paginate --jq '.[].body_html'

# Download a signed URL
curl -sL -o image.png "https://private-user-images.githubusercontent.com/..."
The key insight: 
application/vnd.github.full+json
returns 
body_html
containing JWT-signed URLs for private image attachments. These URLs expire after ~5 minutes.
