What I want is that, each user will have a set of `profile pictures`,
`background images` and other set of `photos uploaded`. These images will
be kept separately in the templates. And if the user wants, he can easily
use (copy) the other set of photos uploaded or images from the background
image set, as the profile picture, and that image will be added to `profile
picture set`. Or if he wants, he can use an image from `profile picture
set` or from the other `uploaded photos` as the `background image` and
similarly that image used from other class will be copied to `background
image set`.
