I use spoonfeeder & Auctiva and they work fine for me. Auctiva is free. Designer is free, scheduler is free, and multiple/supersized pics are free.

There are several services that offer it. Vendio, Auctiva, and Andale are three that I can think of. I've seen some nice ones through SSB. It does cost money to use this service but they provide you with the html for a nice web page to list.
