The thumbnails are not loading or the desired screen resolution is not loading? If it is the desired screen resolution image, try clicking the individual numeric screen resolutions ex.1200x1600 etc., this method always works for me when clicking on a thumbnail doesn't work.
It's all the images...
The forum avatars load, but not the actual images themselves. I suppose that it may be that images.caedes.net is giving me some troubles.
I'm accessing through a LAN, but even before, when I was using ADSL, the images wouldn't load...
I just realized thatt I have had the same problem, but it was only with one or two thumbnails on one page. Have you tried the refresh button? Have you tried clicking the resolution links under the individual thumbnails?
I'm also accessing the site from Japan, if that's a big deal...
