Nexus Dropbox Album

I recently got a Google nexus and now I have many pictures saved onto it. In my gallery there are three albums that I did not put there. One is a dropbox album with my pictures in it, and the other two are albums with pictures I have never even seen before. None of these albums will allow me to delete them and I don't even have a dropbox account. What do I do??

If you used camera upload to Dropbox, it will upload all the pics on your camera.
You can turn off or not use Camera upload.

If you have a Picasa/Google whatever account, those will show up, too.
