I added a [thumb]nn[/thumb] tag (where nn is a number) allowing to make a imageshack-like thumbnail link for internal images.
Example:
http://www.imcdb.org/vehicle.php?id=56600#Comment233016
as the Explorer in episode 3.14 was the same picture as the Escape listed for the series, it was not useful to upload it on imageshack as it was already hosted on imcdb.
