You may have noticed that some of us have our actual character image from battle.net, as well as race, class and level, displayed next to our posts. Here is how to do that:
Click on your name in the upper right-hand corner.
Select User Control Panel.
On the Profile tab, scroll to the bottom and fill in these fields:
Battle.net region (us.battle.net)
Battle.net character realm (most likely Stormrage)
Battle.net character name (the name of your main character)
Submit your changes and check out one of your recent posts.
Note that if you have a custom avatar, you may need to remove that before your battle.net character image shows.
