A quick temporary fix would be to change tile2.php to unlink new tiles 
if there is an existing tile.

And then hard link all duplicate tiles.

I highly recommend the script "faster-dupemerge" from: 
http://www.furryterror.org/~zblaxell/dupemerge/dupemerge.html for this task.
It has an extremely efficient duplicate finding mechanism. (low memory 
requirements)
