If you want to use the group's photo album, you can upload photos to :
https://s169.photobucket.com/albums/u229/BoxerCentral/

Album is called BoxerCentral and the password is boxercentral.

While you can easily post photos on this board directly from your computer, for those that need to post an avatar, this is where you would go. Simply upload your avatar to PhotoBucket and use the URL you are then given to link to.
