It appears during the recent data migration of the TFA Cosplay webhost, none of the required applications, such as unzip or imagemagick were installed on the new host. The gallery requires some of these features to display itself properly, which is why none of the thumbnails are currently up. I actually have Anime Expo 2011′s pictures processed and uploaded, but until the required applications are installed, the gallery is going to be running in a half assed mode.
Hopefully this will not take too long. More info as it comes.
Update - Also have AM2's pics uploaded as well.
