Yeah, I know, sounds too good to be true, doesn't it? It's kinda true. LOL So, what is it?
It is called Adobe Photoshop Express. It's a web-based version of Adobe Photoshop which means you do not download anything to your computer. All you need to do is register (for free). You upload your photos, use the editing tools, share it with friends and family and store your photos online.
The full version of Adobe Photoshop is complicated for some users, this Photoshop Express version is easier to learn. More or less, this is just like Photobucket or Shutterfly.
Right now, this beta version is only available for US users. I'm sure it'll be available for the rest of the world soon enough.
