online image manipulation

I was looking around for online image manipulation programs. I found a few and all seemed quite basic (no real turbocharged web2.0 one), but iaza caught my eye … basic but lots of pictures of the site developer’s Tibetan spaniel Niro!
IAZA - image manipulation and cute doggies!

The other one that seemed interesting was wiredness which is quite basic in functionality, but clearly aiming to be zappy in its interface … and has an API so you can send images to it from other sites for manipulation (what I was looking for).
