Does anyone know of a tool that would stitch screenshots together appropriately?

I have found that if I press Print-Screen with KeyClone active all three WOW's take snapshots... I was thinking that screenshots taken this way would be most impressive if people could see it as the player does... in my case 1280x1024 with two 640x512 windows stacked to the right side....

I know I can stitch them together manually in Photoshop, but thats a pain in the ass.
