Jordan,
First make sure it is only 120 x 120 pixels
Next go to photobucket.com and start an account
Next upload the pic to your photobucket account
After you upload the pic copy the first tag under the pic and paste it in the bring my own avaitor window in your profile
If that doesn't work, right click on the picture and go to properties. On the properties menu hilight the url listed (http//photobucket.cometc.etc.etc.) and right click on the highlighted url and copy it and paste it in your avaitor window in your user profile. If you follow closely, it will work. If you need more help PM me and I will help you out 1 on1.
Brian
