Avatar images manipulated on upload?

[Freestyler]

I'm wondering if it would be possible to have a system on vB where users can upload an image to be used as their avatar, and when they upload it, this happens before the image is actually inserted into their profile as an avatar - the image they uploaded is taken into Photoshop, where an action is performed on the image, and then it's saved with a special number or the username of the member, as a transparent GIF - then this GIF gets automatically inserted into the users' profile as their avatar.

Is it possible to have something like this?

Apparently there are scripts that merge two images together remotely?

Any info/help on this would be much appreciated!
