Photos appeared, can't delete

[lilyhubb]

I recently updated several of my apps, and not too long after I found two new albums in my phone, one labeled "Profile Photos" and the other "Drop Box." They are all from facebook and have a little shutter symbol in the bottom left corner. I can't delete them. When I highlight the album or one of the pictures, the option to delete does not come up. And I can't seem to find these photos when I open up my files on my computer. Does anyone know how to delete this photos or at least find them when connected to my computer?
