How to remove "Browse Exhibits" link and image from the bottom of every page

Hello!

I’m using the Big Picture theme, and at the bottom of every page in my exhibit is a link that says “Browse Exhibits,” and an image representing an exhibit. However, I do not want this link and image to appear on every page. I only have one exhibit on the site, and each page is pretty short, so the link and photo on the bottom creates a confusing user experience.

How can I remove this? I’ve looked everywhere and can’t figure it out.
I also tried temporarily deleting the footer php file for both the site and the theme, but my problem was unchanged.

Thank you so much!

In the interest of keeping conversation consolidated, I’m closing this thread in favor of the issue on Big Picture that was filed at the same time.
