how comes that not all characters has a picture shown on their profile on eu.battle.net?
fx:
my pala : http://eu.battle.net/wow/en/characte...acona/advanced
my friend's warlock : http://eu.battle.net/wow/en/characte...ariah/advanced

is it random who gets a picture and who doesn't, or is it something you have to activate?
was just wondering..
