Hey Terry ..... some people use there own websites to put there pictures up and then hyperlink them to here. Others will use a hosting site such as RonUSMC's site and then hyperlink from that one.
I find it easier to use my own site, I have a little more control over it that way.
As far as pics go, I use a digital myself but have many 35mm pics that I scan and upload. Whichever works for you.
Happy Modelling and God Bless
