Canned Gabbiar, the reason that first image you posted won't work is because the forum you have attached it from has restrictions on guest attachment viewing. Your signature was probably posted in another forum which allows guests to view attachments.
In order for us to see non-guest attachments, we'd all have to join the blizz forums which is something we all ain't gonna do!
It's best to just attach them here, as well as the blizz forums, depending on who you wish to see them.
