I thought about buying photos for a website I own of interesting places; and the photos would include my domain name on a simple sign. My site is news oriented and some of the sellers would deliver a blog report with their photos, and other sellers would just deliver photos that are used more for promotional reasons. The problem is is that I believe some people would rip-off pictures from the web and digitally alter the photos to include the simple signage that I requested in the photo. Any suggestions on how to deal with this situation? One possible alternative is to request youtube videos because it is much harder to fake video; but, I still like the still-photo idea too. I'm not a photo expert and this is why I joined this forum to ask these sort of questions. Thanks in advance.
