I have searched Drupal numerous times and I have not been able to find an answer to a specific problem that I am having, so please forgive me if this has been answered recently. I am using Lightbox2 with Ubercart, and for some reason the thumbnails in the teaser are now missing. I haven't changed anything, the other day while doing some QA I noticed all that is showing is a grey line where the image should be. Can anyone tell me how to fix this? It is happening in both firefox and IE.

Thank you,
H
