I think the maximum size for them is 40 x 40, but I'm not sure, so find a picture smaller than that. Then right click on the picture and click properties to view the size. Then right click again and click save picture and you can save it to a file in your computer. Then go to user CP (on Pet Talk) and go to edit options. Then go all the way to the bottom and it says would you like to change your avatar or something like that and then it says next to it a little button that says create your avatar, and you click on it, and presto! You meanie you took my name! Lol!!!
