With the recent update of the PlayStation Network Portable ID, now including trophies, I have changed the way in which your gamer cards are viewable on the posting and profile pages.
If you have associated your PSN ID to your account, it will now display under your signature. This will not be visible at first, click the 'Show Gaming Cards' button, to view these and then click 'Hide Gaming Cards' to hide them again. Your Xbox Live GamerCard is also now in this section, if set. Because the full Portable ID is large, we have decided to not use these as avatars any more.
Portable ID's are not automatically assigned and messages will appear in place of images if a user has not set theirs. To set up your Portable ID, visit
http://eu.playstation.com/, sign in using your PSN ID and follow the onscreen instructions.
