The KOA should be good to go for a picture(s) upload.
Just to be sure, I'm assuming you clicked the "edit camgground" link in the blue tool bar and then clicked the browse button to locate the picture on your computer?
If that was done and you received the "not authorized" notice, send the picture to me as an attachment to an E-mail here:
RVrsRUS@AOL.Com and let me try adding it.
