Photo Editing Tools
Dumpr is 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.
A.viary is a hardcore photo editing app, kind of like Photoshop without the price tag and disk install. But it’s way cooler than that. It’s a whole lot of really interesting editing abilities and a whole community of people doing their own thing with the tools that makes this one a great choice. Note: it’s still in an invite-only beta period.
Picnik is a lightweight photo editing tool that gets me through pretty much all of my needs right now. I use it about twice a day, and have found that it does most everything I need from a photo editor. It’s not really good with batch-based activities, but if you’re into editing things one at a time, this is for you.
Skitch acts as a screen capture and annotation tool. It’s super easy to use, has just enough tools to be useful but not so many that you feel bloated and misunderstood. I use it to do lots of odd jobs on capture screens and little images from web pages. Definitely good to have.
