cURLing sites for images

OK, I give up (for now at least). I've been trying to figure out a way to run a single script and download my favorite comics. The problem is that: 1. The URLs include numerous websites (and the image is hosted on another server from the original) 2. The filename can change but has the same basic name What I would love to do is use cURL to load the list of URLs, and then save all the images within each page into a directory based off the date. What I have not been able to figure out how to do is use CURL to open the page and save all the *.gif and *.jpg files only. Anyone have a good pointer on this? I've been going through the archives and some tutorials, but most seem for posting to another site, not snagging files. Thanks, Wolf
