You could either post the pics with any distinguishing features blaned out (make sure the thumbnail is the same), that way she can't freak too much if she finds out, OR post some non nude pics, we'll say if we want to see more, and you can show her to say "these guys want to see more of you, how about it?"
OR you could post them, but if she finds out, I doubt she'll be your girlfried for long
