With powerpoint it would be alot of work and I'm still not sure how we would get it to cycle back through the wrong ones. I am sure Excel could pull this off. You could place all the photos on a worksheet with the names right next to them. Then change the font color or something so you cant see the names. Program a macro to the picture that when clicked will go to the next cell and reveal the name then a message box could come up that would allow you to put in Y or N for if you got it right or wrong then the message box would take that info and put it back to the next cell so all that info is in 1 row. It would then recolor the text or hide it so you could choose another picture. The best thing is when all of this info is in you can then go back to it and try to get the other correct. If this sounds like a way you want to go lets talk to somebody about getting the macro code alltogether since Im not quite sure how to get message box text into a cell but I know its possible.

Thanks
