I was looking for a workaround for having the AW shopping cart do the 18+ images as well as the regular images. I think I found a partial solution. Thanks to this site: http://theidiot.freehostia.com/tag/iframe-tricks/ I used an iframe on my site to display part of an AW page.
NOTE: You will need to view image in a seperate window to see all the text in it.
EDIT: I see the iframe behavior in Chrome is crap. Oh well... I'll try using Ajax next. :) OK, I'm looking at things like this at the moment: http://stackoverflow.com/questions/2176342/embedding-part-of-a-web-site
