Hi,
If you mean the Auctiva logo between the bottom of the template description area and the eBay free image, I'm seeing no gap. This sounds similar to an observation by another member on a thread last week. The member was seeing a gap, but several of us didn't. That seemed to mysteriously clear-up. Here's the thread:

One of the description tags is required. I'm now seeing the period with paragraph code <p>. </p>, which appears to have slightly widened the top margin between the scrolling gallery and top of the template.
