You don't need to do that at all. Sandy is the only person here who has anything like that set up, and even he doesn't have everybody.Most quests lately have trended towards not even showing the questees at all, only showing pictures of the sets and NPCs the characters interact with. You're free to construct the heroes on your quest if you have the parts, but it's by no means a requirement. Also, most people don't change their photos terribly often - only when they feel it's time for an update. Between updates, if you do use their character, typically you base it on whatever is shown in their current picture, not on what their gear looks like.
