# GitHub Attach Images

Attach images to GitHub PRs or issues by hosting them in a scratch repo.

## When to use

- Adding screenshots to PR comments
- Attaching images to issue comments
- Any GitHub comment needing embedded images

## Setup scratch repo

1. **Clone or create scratch repo**
   ```bash
   git clone git@github.com:<USERNAME>/scratch.git /tmp/scratch
   ```
   If it doesn't exist, create a public repo called `scratch` first.

2. **Folder structure**
   ```
   scratch/
   └── github-attachments/
       └── <org>_<repo>_<pr-or-issue>/
           ├── 01-screenshot.png
           └── 02-screenshot.png
   ```

## Add images

1. **Copy images to scratch repo**
   ```bash
   mkdir -p /tmp/scratch/github-attachments/<org>_<repo>_<number>
   cp /path/to/screenshots/*.png /tmp/scratch/github-attachments/<org>_<repo>_<number>/
   ```

2. **Push to GitHub**
   ```bash
   cd /tmp/scratch
   git add .
   git commit -m "chore: images for <org>/<repo>#<number>"
   git push
   ```
