Hi Thomas,
I'm really not sure whats going on there. It seems to be able to find the images since its creating links and labels.
If you'd like me to investigate further, I registered on your site as jaudette. If you'd like to temporarily make me an administrator I'll have a look around and see if I can figure it out. You can always remove me from the admins role afterwards. To add me as an admin just go to the member list and click the gears next to my user name and then on the Roles tab add me to Admins.
Is this site part of a multi site installation or is it just one site?
Best,
Joe
