As you may know, Google+ ate up the online photoeditor Picnik. The good is that there are now no paid functions. The bad is that some functions have disappeared and that you have to work inside Google+.
As of June 21, 2012, Rippet has taken over from good-old Picnik. All is the same as it were before. And for a limited time all functions are free to use.
Enjoy just like this!
