There has been a reported (and confirmed) issue with images being added to the website but not displaying as required in thumbnail view mode.

I have tracked the issue down to a duplicate image data type definition in the site data types registry. Unfortunately the fix, which is to remove the broken definition has unmasked a deeper problem with the misbehaving images, and I was forced to remove them from the website.

I have run a data integrity scan across the site and removed the broken images I have found. In all 44 images in "The Gathering 2008" fell victim to this flaw.

I do apologise for any inconvenience, but this is the only way to guarantee the integrity of data in the site.
