Banners In Sidebox

In Responsive design, I put a couple small banners in a sidebox on both product and category pages. On the product page it works fine, but on the category pages, it stretches the banners so they are way too big and obnoxious. Anyone else seeing this? I wanted the same banners on both…

Thanks for any help :)

I was able to get a block added on the left for the banners on the category pages (not quite sure how since I tried so many things) but there appears to be no way to add a grid or block to those pages on the right of the main content. I wanted these banners on the right as they are now on my old site…but I cannot add a grid. I went into widget mode and got one added right where I wanted it but it does not appear on the pages at all. sigh

Any suggestions??
