Thanks for the quick reply, but that's not what I was looking for. There's two options I see in Admin; one is under:
Show Random images on Index page?
I have it set to yes so it shows four random ads on the bottom of the pages.
The other is:
Random Ad - Display Random Image?
I also have it set to yes. It shows one randomly selected ad in the sidebar.
These work as they should.
Basically what I'm looking for is a way to show only auction ads
in their own side box - separate of any fixed price ads. Like a "Random Auctions" box in addition to
the "Random Ads" box. I don't see a current way to do this.
