Next time I should probably word my question better and post it in the right section but thanks for the help.

Actually my description is a bit lame. I'll have another go. Is there a way that you can develop a photograph so that when it gets exposed to sunlight it disappears. The photograph would be put into an envelope in the dark room so that it would not be exposed to sunlight until it is opened...

Hello I want to put a photograph in an envelope and when the person opens it and pulls out the photograph, it quickly disappears. Is this possible and if so, how?
