ImageCanvas
Transform any image into stunning Minecraft map art with a single command!
ImageCanvas is a powerful Paper plugin that lets you display images from URLs directly onto Minecraft maps. Create breathtaking galleries, pixel art displays, or custom decorations using multi-map grids up to 15x15 in size.
Features
Easy Image Import
Simply paste an image URL and ImageCanvas handles the rest. The plugin downloads, processes, and converts your image to Minecraft's map color palette automatically.
Multi-Map Grids
Create massive displays spanning multiple maps! Support for grids up to 15x15 maps (that's 1920x1920 pixels of display space). Perfect for large artwork, server logos, or detailed builds.
Auto-Placement
No more tedious manual map placement! With the -auto flag, simply place one map on an item frame and watch as ImageCanvas automatically fills all surrounding frames with the correct tiles. Works in any direction - horizontal, vertical, or even on floors and ceilings.
HD Quality Mode
Enable -HD mode for superior image quality using Floyd-Steinberg dithering. This advanced algorithm produces smoother gradients and more accurate colors compared to standard conversion.
Web Upload Support
Playing on a shared host like Minefort or Aternos? No problem! Use /imagemap upload to get a secure link to our web uploader. Upload images directly from your browser without needing server file access.
Persistent Storage
All your image maps are saved and persist through server restarts. Maps automatically restore their images when the server comes back online.

Tips & Tricks
- Optimal Sizing: Plan your grid size based on your image's aspect ratio. A 16:9 image works great as 4x2 or 8x4.
- Frame Preparation: For auto-placement, place empty item frames in a grid pattern before placing the map.
- HD Mode: Use HD mode for photographs and complex images. Standard mode works fine for logos and pixel art.
- Large Displays: For very large grids, consider using invisible item frames for a cleaner look.
