We had this idea already on the list, though the proposed solution was 
to use Imagemagick or GD2 to do the job (cannot remember right now).

Anyway, nobody with programming skills thought it was worth the hassle ;-)

Besides when would you apply the removal? While the image comes into 
upload? Certainly not, as it would change the image. When it comes into 
the temp directory? Fine, but you don't want to have ALL images 
duplicated in the temp directory. Sidenote: IMHO storing the images all 
in one dir. isn't such a good ideas as some filesystems have performance 
penalties with very large dirs.
