Okay, so I am in the design field, and I know about copyrights. But it is not like I can take photos like these, let's face it, I would not actually want to put myself in some of the predicaments that these caps have. Sure, it's nice to fantasize about such things, but reality can be a bit different.
So The fact that I plan on making no money of these images should help with copyright infringement. If I do happen to use one of your images and you don't like it, you can email me and I will remove it immediately from my page. No harm done.
Let's leave it at that, and I will hopefully not have any problems.
