i recently came across three free photo editing links that i thought might be of interest:
ez rounded corners
i was excited to see these, because my eee is limited on space and i am happy to use these free, bare-bones, no-download options when possible. basically, i think the photoshop one has more bells and whistles for more elaborate projects, but picnik is just more ideal for easy, quick jobs. ez rounded corners is just that, a fast way to nicely round image corners. enjoy!
