Snipshot (http://snipshot.com/) previously called Pixoh, is a very-good Ajax-based editing tool that stands out because of its above average design and the fact that they have an API into their service. It’s like PXN8, but more intuitive. Snipshot can edit big pictures up to 10 MB, or 25 megapixels (5000×5000 pixels).Snipshot is very easy to use, just submit a URL, browse your computer or you can simply play with one of their sample images - no login required. You image will be display on screen in edit mode where you can rotate or resize your image. Finally, you can save your image to the desktop in several different formats.

Snipshot allows you to import pictures from Flickr or any website using a bookmarklet. It also allows you to export and save images in a range of formats (JPG, PNG, PDF, TIF, PSD, and BMP). Check out Max Kiesler’s great screencast.
