Maybe I can help until LOM gets back from Canada. Hosting requires a web address. What I did was build my own personal web site from Tripod. It costs about $20 a month. Mine is brentramsey.com (Ramos) if you want to take a look. It's under construction so don't expect too much. Since my brother makes TV commercials, we hope one day to use it for his business. Now it's only purpose is to host our sigs. It's a project for the future.
Anyway, once you get the sigs on the site using the Photo Collection build (this is a piece of cake) you right click on the sig, then click Properties, and finally copy the web address to your computer's clipboard. The last step is to paste the web address into the IMG dialog. These last steps are explained in detail on this forum; I think by Druid (it might be RD).
