Dang, Otto, you’re quick. I came back 6 minutes later to say I’d figured it out and you’d already replied! Thanks!

So, I wanted to get the template_url so I could use it to point to an image inside my theme. I was using bloginfo(template_url) to try to insert into a query parameter string when I should have been using get_bloginfo(template_url).

So, the solution code is:

wp_list_categories('title_li=&show_count=1&orderby=count&order=desc&feed_image='. get_bloginfo(template_url) .'/images/rss-icon.jpg');

Thanks!
