As to baffo's example in the previous WU; a much easier way of doing that (no need for a slurpfile) would be:

wget -r -A jpg http://vast.porn.site.com/people-fucking-with/stones/

If you give the root directory, it will grab everything in that directory. The -r option means recursive (it will follow links and go into folders and stuff). The "-A jpg" means "allow (only) jpg files". Another useful parameter is the -l# (hyphen lowercase-L number). This specifies the levels deep to go; i.e. follow hyperlinks two levels deep.
