Mutt -
I think your are confusing this site with the Custom Game Call Sales site. You dont have to use photo bucket or any other hosting service on the game call sales site. That does not apply to this site. Two different sites, two different programs.
However, if you have your own web site, you can open your C panel and create a folder for you pics and upload them there, no need to use a hosting service if you have a site. Most have more space than you will ever use.
