If you’re no Photoshop guru, but you have fun applying different novelty filters to your pictures, you might like Dumpr. It’s web-based, very simple to use, and has a pretty decent library of effects: sketch, Lomo, reflection and jigsaw puzzle, to name a few. You can upload photos from your own hard drive, or paste in URLs from some of the major photo hosting services, including Flickr and MySpace.
Dumpr isn’t really meant for advanced users, although buying a Pro account will get you access to a few more effects. Despite the … interesting … choice of name, Dumpr is pretty fun to play with, and it’s great for quickly doing things to photos that would take a while for a novice to learn in Photoshop. It also has a few Flickr-specific features, like searching for pictures similar to your favorites, and rating Flickr photos. We’re still not sure about telling our friends we’re going to Dumpr some photos of them, though.
