📐 Tampermonkey GitHub Image Resizer

A Tampermonkey userscript that automatically converts uploaded image Markdown in GitHub Pull Requests into an HTML <img> tag with a customizable width.

This tool supports all GitHub image upload methods — including drag-and-drop, paste, and the attachment button — and ensures consistent visual layout for embedded images.

🚀 Features

  • 🖼️ Automatically converts this:

    ![alt text](https://github.com/user-attachments/assets/...)

    into:

  • ✅ Supports all image upload methods:

    • Drag-and-drop from desktop 💾
    • Clipboard paste 📋
    • Attachment button 📎

  • 🔁 Converts image Markdown to HTML <img> on-the-fly — no need to manually edit it.
