wget can give us warez and pr0n boys a particularly sweet feeling, when you manage to latch onto the naming scheme of a site, write a nice slurpfile full of URLs all of the form:
http://vast.porn.site.com/people-fucking-with/stones/pic0001.jpg
http://vast.porn.site.com/people-fucking-with/stones/pic0002.jpg
http://vast.porn.site.com/people-fucking-with/stones/pic0003.jpg
...
and then fire up that bad boy with

wget -t 30 -i slurpfile

Just sit back and watch the stuff roll in ...
