Adobe released the public beta version of Photoshop Express today. Being flash based, its contained in-browser with no need to download stuff; and being aimed at the casual photo editor.
I used it this morning, and its pretty good. It has most of the main features from regular photoshop, but doesn’t have an API with flickr so thats a drawback.
I imagine myspace pictures will be upped a notch with this.
