I think I see the unique factor here: clicking images and then the search engine logo allows you to use alternate sources. While this is a nice idea (although Web should have at least Google) I kind of feel combining many search engines, stripping out the duplicates, and creating some sort of combined ranking could be a much better idea - rather than performing several searches. Eliminating categories and using heuristics to provide a single subject-detectable input, while tricky, could be even better.
