Why do I feel weird having a "pretty" Facebook picture?

Last weekend I went on a road trip and ended up having a sort of impromptu photo shoot in front of Mount Shasta because this guy had a really nice camera.

I’m really happy with how a lot of the photos turned out (especially with the mountain in the background). It’s the closest thing to modeling I’ve ever done. He took so many photos (!) and posted them on a Picasa album so I could see them all. He took some amazing group shots as well (mostly funny jumping ones).

Part of me wanted to make a Facebook album of some of my favorites (including the group shots). But when it came time to do it, I couldn’t. I also wanted to change my profile picture to one of the photos he took, but found myself unable to keep it as one of the really glamorous ones. I felt silly and narcissistic. I keep changing it back to either me making a really goofy face or me looking sort of plain and smiling. But the photos even have his signature in the bottom right-hand corner so it’s obvious that they’re semi-professional…what’s my deal? Why am I so insecure? I admitted to myself that I liked the photos!

EDIT: I was just about to post one here for you guys to see an example, but I feel embarrassed even doing that! And this is my haven!
