Drupal.org theme preview images not showing in Firefox

When I look at drupal.org's list of themes at http://drupal.org/project/Themes with Firefox 2.0.0.13 for Windows, none of the screenshot preview images for themes shows up in the teaser list. (The screenshots do appear when I follow the link to look at a page for a particular theme using Firefox. And the screenshots do appear in the teaser list when I look at the list using IE.) Is this something that can be corrected at drupal.org?
