Simple web icon editor

Question

My website uses 16 x 16 pixel icons (stored on the server as PNG files). I would like to provide functionality to users of the site for editing these icons. My site already uses jQuery and jQuery UI, and I am familiar with them, but any suggestions are welcome.

EDIT

It seems to be harder than I thought. I think I'm going to postpone an attempt to include this functionality in a website. But if anyone knows about a JavaScript icon / raster file that is no longer mentioned in the stream, let me know.

Answer 1

Here you can get inspiration.

I do not know any free, ready-to-use editor without a license.

Answer 2

Check out http://www.jpie.net/ (also requires PHP), this is the hardest thing I found, but not too sure how much the actual “editing” users should do (or can do 16 pixels on the image)
