To the extent its possible, I really favor names like Screenshot Captor, Find and Run Robot, etc, rather than having the words run together. Looks neat with no jargon.
I really love Stephan's idea to put information that the screenshots were made by Screenshot Captor. My preference would be to always include the words "made by." Otherwise, it looks like the name of the program that is being shown on the screen is Screenshot Captor, rather than that the image is made by Screenshot Captor.
An additional refinement: I would like to see the words "Screenshop Captor" larger than "donationcoder.com." Just looks more neater.
