Image attachment?

I would like to post some images in the avian behavioral forum. Being a brand new member I checked out if there were size restrictions(found them) and how to attach them.
I noticed that there was no 'Manage attachment' spot for posting, as it states in FAQ. I'm familiar with the 'Image Insert' button, but see that I can only use an off-site album, which I don't have. Can I no longer upload from my computer?
Thanks,
Mary

Mary, only members can use the BPN server, forum contributors have to use their own web space and use the image insert button.

Sorry, Alex, I didn't see that. Thanks!
