Hey all, I'm in need of a PHP/Javascript powered Sprite editor. One doesn't exist that works in IE 8 or newer (very important so I can use it when I'm supposed to be working

), I've looked all over the internets. So I propose we get together and make one. Nothing fancy, just need to be able to edit an arbitrary sized sprite (let's say 8-64 pixels width/height), with a fill and a pencil tool and a nice palette system (maybe something like tilestudio?). The software needs to be able to save to the server it's hosted on, and be able to download it later. It should have a big blown up editor part and a little mini tiled preview section off to the side to see how it looks. It would be nice if it could support animated tiles but that could come later.
It can be in any format really. I can build and of course, share my own converter for whatever format you choose, but I don't know javascript so I'm at a loss for creating such a beast myself. I propose that one be created off of the elFinder 2.0 code base, as a plugin or extension or whatever, because it's got all the file system management stuff built in, all one would have to focus on is the sprite editor aspect and a file format. elFinder works really well for editing text, it would be cool to be able to edit sprites.
All for free? No, I'll pay a reward! I'll give you cash/paypal/giftcards and I'll help support the project as well with code hosting and/or ongoing support. Heck I'll even host a sprite server publicly for us TGCers to share sprites!
Is there anyone here that can do it or wants to do it? If so, name your price! I bet other people here might find it useful too and would be willing to throw into the pot.
