Instant Sprite - CSS Sprite Generator

I’ve been working on a project to make generating CSS Sprites faster and easier. It is called Instant Sprite, and available at http://instantsprite.com. You can drop the images right into the browser (or open them up in a file input) and it generates the sprite in the browser, with no file uploads. You can check it out and use some sample images provided if you don’t have any images available.

Instant Sprite uses HTML Canvas and the FileReader interface to read images from your hard drive - this prevents you from having to zip up all the images before passing them off to the sprite generator. You can also preview your changes to CSS tweaks in real time, so you don’t have to resubmit if the file match regex isn’t doing what you want.

I’d like to give credit to Aaron Barker for helping out with a lot of feedback and UI suggestions.

I made it for myself so that generating sprites was easier, but put it online because I think it might be useful to others, too.
