“Does That Website Really Own The Photo They Just Gave Me Permission To Use?” Not Likely!

I have found a few pictures on the Internet that I would like to use in my book. I have seen them on several different sites. However, I can’t seem to locate how or where to buy the rights to use them and I haven’t been able to find them (or anything similar) on the sites that allow you to purchase rights.
One website has given me permission to use them but I am not at all comfortable with this because I cannot be sure that THEY have the rights to be using them!
