Well apparently in in order to take a photo of your screen on windows you need a print screen button, which apple keyboards obviously don't have since in osx they do it a different way. So how do i do it without the button?
Hit the Windows key, type snip, and there you go. If you want to take a fullscreen shot, hit the arrow next to "new", and choose the appropriate option. It's all fairly self explanatory, you can figure out the rest for yourself after 10 seconds of playing with it.
