Fantasy Football Helmets

I just created two fantasy football teams on Yahoo and not like a helmet designs provide default Yahoo, have created my own images for both teams. Have successfully loaded both, but when I go to 'Edit Team Settings "and" Choose your own image, it changes the image of the headset for both teams - and not just the team I was assembly. How do I get to retrieve the image for a single team at a time?

A profile, a helmet.
