I first heard about this software during a BAW session, when I knew nothing about working with pictures (not that I know much now! :-P!!!). Loved it immediately 'coz of its intuititive interface. Still today, I'm fascinated by how I can copy (while at the same time compress) tens of pictures from my mobile devices to my hard disk in just a couple of clicks and seconds!
Definitely worth trying!
Thanks Gladys and Paul for sharin these photo manipulation sites. We all need them nowadays.
I must confess I'm totally in love with Flickr together with Picnik . It gives lots of editing options, including adding text, special effects, etc and when I'm done, it saves directly to my Flickr account. Lots of fun and very useful to create tutorials, for example.
