Good, Free Images with No Licensing?

Hey everyone, I’m not really sure if this is the correct forum for this question, but since I am unsure of where else to put it and I am doing it for a game, I figured that this would work. I am looking for a site that has quality images for free, but that I don’t have to worry about licensing rights and things like that. Does anyone have a site (or 2) that they really like to use? Specifically, I am looking for some maps, of the United States and Europe, but really any site will do, because I want somewhere that I can go for modeling resources as well. is pretty good for textures.

since you do not really use referece images in your personal work, and the building or whatever depicted is not copyrighted, as far as i know you can use any reference images as far as it does not look exactly the same. (not 100% sure as i said)
