Most people cheat by looking at the file name, but that's been caught onto and fixed (mostly). Google images is just guess and check, you'd never find it, however I know it can be helpful for hints, but yes, reverse image searches,
if done right, are extremely accurate. It's obvious, I suppose, I guess I'd just never thought to use them before. (I am/was plenty aware people cheat with the former methods, I guess I just didn't now of their awareness of such search abilities. Most other methods have been blocked or don't reveal much.)
