Probably on the fly it is unless your server is pretty underutilized.

If you have ImageMagick, it can easily be done by making a UserTag,
though, and only doing it when the file doesn't exist already.

The shell script for doing that is:

	mv __IMAGE_DIR__/items/filename.* __IMAGE_DIR__/thumb \
	&& mogrify -geom 80x80 __IMAGE_DIR__/thumb/filename.*

I think there is even an example in some UserTag in the admin
space -- I believe it is called image_collate. It is pointed
toward batch-making thumbs, but it should be useful.
