Pixlr -Pixlr is definitely one of my favorite web-based image editors. There are several versions depending on the type of editing you want to do. The Pixlr editor is the full photo editor that I have found to be quite good for many image edits. Pixlr express offers some quick edit tools in an easy format and Pixlr-o-matic offers some quick vintage effects for your photos. If you want to create your own image you will want to use the full Pixlr editor. One of my most favorite features of Pixlr is that you can create a free account and save your images in your Pixlr library. This means if you working on an image and have to leave that computer, you can save your image in your Pixlr library and easily pick up where you left off on any other computer.
