to make the avataar workm load the picture in paint, go to image then attributes, and change the pixels or wotever to 80x 80 aint it??? then it will make it the right size
the reason why this did work when u did it cos u changed the size of the actual pic, but the white will still be there...so it takes room up....
what i have said will work (p.s use common sense when doing this)
