since I use ezcheckout, which breaks the cart out of home.tpl, I don't have this issue anywhere else. Yes, a small issue, but I consider any security error on my site to be a bad thing.
All the stuff on the lower right - shopping.com rating, BBB, and Geotrust images are all called from a .tpl I made called trust.tpl, which is called in home.tpl. I was trying to make it so only the shopping.com was omitted from the https pages.
