Download the
wowhead client. This should be what you are looking for.
The Wowhead Client is a little application we use to keep our database up to date, and to provide you with some nifty extra functionality on the website!
It serves 2 main purposes:
It maintains a WoW addon called the Wowhead Looter, which collects data as you play the game!
It uploads the collected data to Wowhead in order to keep the database up-to-date!
You can also use it to keep track of your archaeology projects!
you will need to log onto each character you want on wowhead.
I want to express that this addon only collects data, it
does not record your battle.net username and password. It
does not link the accounts as that is not possible. It does however assign your characters from warcraft to your wowhead profile.

The best and easiest is to use the
wowhead client. Log into each toon and then upload the data. I think you can also search the toon and then claim it, but I do not have any unclaimed at this moment to do so.
