A browser-based single-purpose image editor. It allows to add predefined overlays to images loaded from the web or via file-api.
See it deployed at billy.nodester.com.
Editing the images happens completely in the browser using @kangax`s fantastic canvas-library fabric.js.
The only active component on the server is a proxy to circumvent the same-origin-policy.
This tool is supposed to make it easy to contribute to the facebook-group The Billiam Van Kiddur Appreciation Society.
