Problem: my avatar has a boring white background and yours has everything from a castle, to fire and brimstone, to a forest to who knows what else. what items have these backgrounds? is there a background store i dont know about? do you pay for these items?

there are CI that have the backgrounds and there are some EI's.

thats the price guild. it will show you all the items and it will let you know the price.

to get these items you have to have someone either sell them to you or give them to see. see the exchange thread and the charity threads to find the items you desire. the simple background i have in avatar comes from the toybox though, and you can buy that. it comes in a variety of colours. but its not the castle or the fire.

good luck!
