You could always use my
Comic Plucker script (Plucker not required, and don't forget to read the
README file).
It hits the upstream comic sites, fetches the URLs from the pages, fetches the image link from each comic page, and drops them onto your local drive, each in its own separate file, and then builds a master index.html file that links to all of them (sorted in order).
It works great for me..
I rewrote the Python one in Perl because I wanted it to be "self-healing", so I wouldn't have to go maintaining lists of links, urls, images and comic titles. This one populates itself from the upstream comic site directly.
Have fun with it, and if you have fixes/suggestions, let me know.
