not sure where to post this......i want my pic as avatar.......just signed up for photo bucket and uploaded pics......still cant make heads or tails as to how to resize my pic to 90x90 so i can use it here as my avatar??? then wich one do i copy and paste in here? there are like 5 different ways and i tried them all...always says: couldnt determine which image u wanted....or something like that.....i clicked the box next to my pic.......frustrating....wish they would just let u choose file from computer ......grrrrrr
