This sounds really weird: Why don't you ask the guys collecting these images for you? Or did you do this by yourself? Moreover, you certainly have a supervisor. Is he/she not able to help you? It is your master thesis...(not ours) and a master thesis has the aim to prove that you are able to solve a problem and not to know people who solve the problems for you, don't you think so? It is no the result of a thesis which decides about the degree but YOUR ability to work scientifically.
