The images weren't a size issue, I'm not sure how you saw that. There was an image caching script in use at the old host to bring images over here, I guess to prevent broken images down the road. I have re-added it, and will restore the images that resided in it.
Code tags appear to be working for me, can you elaborate a little bit as to what isn't working for you regarding them?
The icon isn't broke, it got changed during the move from the default vbulletin icon.
Thanks for using Imgur.
Those group icons use a custom group icon system in VB, and we have none in that directory, so the alt text is the description it looks like.
These had to have been like this for quite some time as there are no files or thumbnails in that directory at all. I can check a couple old backups when I get home, but that would have been broken before the move as well.
This is tested and resolved.
