I am really starting to dig the integration of Picnik into Flickr. I know it’s not new but every time I use it seems to work better and faster. I love that you can just edit your image right there online and immediately save it either as a new image or right over the old crappy one. It took me literally less than ten seconds to make the adjustments to the photo below and just look at the difference.
And the best part about it is that it’s totally free. They do hide some features hoping that you’ll eventually upgrade to a paid Picnik account but most of the locked features are just added fluff. Cool fluff, but fluff nonetheless and most importantly fluff that you can definitely live without. All of the basic fixes and tweaks are included in the free version.
