A new breed of online image editing tools are bringing increasingly advanced image editing tools to the masses. Sites such as Piknik - http://www.picnik.com let you crop, rotate, resize, adjust brightness and contrast, apply effects and much more. The amazing FotoFlexer - http://fotoflexer.com/Â has an incredible feature that allows you to alter the size of an image without distortion, or remove areas of an image altogether. It's amazing to see: These are just two of a wide range of such sites, but certainly two of the best. They also release their api's so that they can be used in conjuction with a variety of social networking sites.
