Picnik is an online photo editing service. Currently it can import photos natively from Facebook, Myspace, Picasa Web Albums, Flickr, Yahoo Image search and also offers options to upload from a computer or to upload from a website.
Many of Picnik's basic photo editing tools are free to use. Picnik Premium includes additional photo editing features and is offered for a monthly, 6-month, or annual subscription cost.
Picnik has a partnership with Flickr that includes a less feature-rich version of Picnik built into Flickr as a default photo editor. They have also signed up to do photo editing with free website creator Webs.
