Batch Download Pictures From Website

Hi

Everytime I try to download from this site I always get the thumbnails and not the larger pics.

The site is

http://ironmouse.za.org/dragon/

I am trying to get the pictures from each of the characters parts but to no avail.

I would be grateful if someone could help me.

Too many pictures (more than 20,000?) and the large picture link level so deep, I only got a few pictures in the first 1 hour, but after this, I can get several pictures per minute. (512K DSL)
