Hey Bill, I somehow missed your message before, but just now found it cleaning out my email.
Anyway,the Cooliris integration I was talking about does NOT require users to have the plugin - that is a separate thing that they offer. I actually figured out the problem... it was my XML file which somehow was only working with the 2 browsers. I rewrote it so that its now fully cross-browser compatible. If you want to see the Cooliris wall working on my site (without you having the plugin) then you can see it at travis-larsen dot com
