Whole Invex clan list that has broken signatures.

Fixed the ones I could by adding a better imgur whitelist + tumblr.

The rest are on random websites so they'll have to reupload to imgur to fix it.
Me and you could do it for them too by using modCP if they ask us or we stumble across a broken image.
After I add the warning thing you won't be able to post a thread or edit your signature if it contains the broken image which will help.
