The first thing you need to do is find a "host" site for your pictures. RonUSMC , a member here at the forums, has just that kind of site.
Here's a link to the thread that explains the procedure.

After you have your pics hosted, then you can link them to this site when you want.
Just follow the procedures listed in this thread.

Give it a try in the Testing Forum. If you run into any problems, just shout, someone will be along and give you a hand.
Happy Modelling and God Bless
