I've been searching for one as well. I've had no luck. I did find an application that will allow me to shrink the size of large pictures on my BlackBerry to a size of my liking. It makes it easier and faster to Email photos. It makes a copy, so you still have your original. It's called ShrinkIt!
I'm still going to keep my eyes open for a photo editor. That would be great!
