find a picture you want on the net.
right click it, and click 'save picture as'
open the file (i use microsoft photo editor)
right click on your photo. it should say how many pixels in width & height the photo is. you need a max of 100 pixels in width & height.
if you have alot of empty space, click image - crop and do that until you have the part of the pic you want.
so go to image - resize, and make the picture smaller until it is under 100 pixels. then save it.
go to elite, and go to profile - edit options - change avatar
click browse, and choose the folder your avatar is in.
