Stitches is an open source HTML5 & CSS powered application for creating CSS sprites with drag and drop feature.
With the help of a couple HTML5 APIs, images can be drag ‘n’ dropped and the sprite image + CSS rules are instantly generated.
It uses Modernizr to check for drag-and-drop, FileReader, and canvas support (which are currently available only in Firefox and Chrome).
A must-bookmark tool for saving time on creating sprites specially when there are too many images to merge.
Requirements: jQuery 1.6.2+, Modernizr, Dropfile, Flashcanvas for older browser support
Browsers Support: Firefox & Chrome
