Pixlr is a free online image editing application that enables users to create or edit an image from a hard drive or URL in your browser. This is a flash based application that loads in seconds and does not slow down when editing multiple images even with thousands of users online at once.  It is built in Flash and you need to have a Flash plug in (get flash) to get it to work.

It’s not for large RAW images or for printing. It is merely a tool for editing web images to be posted on blogs, news-sites, social networks like Facebook, Bebo, image sites like Flikr, Photobucket etc.
