xChan Directory Dumper

So I've found this nifty program that makes spamming easy.
Is there a program that makes it easy to save the images of a thread? Save page saves thumbs, but I mean the actual full images.

I prefer rc because rc is a command interpreter for Plan 9 that provides similar facilities to UNIX’s Bourne shell, with some small additions and less idiosyncratic syntax.
