# 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.
