Pixenate is another great and free site for online image-editing. Not only does this site offer the features of cropping, resizing and rotating images, but also offers others like sepia, horizon adjustment, changing the lighting effect and even a zoom feature. Its GUI is more appealing than the Picnik GUI, where it provides a grid of thumbnails to operate on the images. Operating this site is pretty much similar to Picnik. Simply upload an image and start working on it. Cropping, resizing and rotating are with little variation from Picnik. The sepia, whitening, red-eye removal, horizon-adjust and zoom are what are eyecatching in this site.The whitening feature can be used to produce pearly-whites on the faces of smiling people. The horizon-adjust allows for tilting the picture at angles to the horizon in order to produce certain kinds of effects, and the zoom in and out thumbnails are great for picture magnification/shrinking.
