Using Version 1.3.8

I had transparent png for my background.

It was applied to the body tag through the css stylesheet.

Long story short, if you have a transparent png as your background, the additional images on your product pages would just flat out disappear.

This only happened in IE6 as far as I tested. I noticed no problems in Firefox, IE7 and Safari.

To fix the problem, I simply sacrificed the transparency and made the file a jpg.

Another workaround would be to create a conditional stylesheet for IE6. I believe that there are additional hacks that can be implemented to have IE6 use a transparent background, but in my instance it didn't bother me to leave it out.

Hope this helps someone, this was the last place I thought to look. I skipped over it to fix another IE6 error and ended up tripping over the solution. Probably would not have found it otherwise.

Probably not a Zen Cart error, but good to know.
