Welcome! This should be an interesting build, I'll be keeping an eye on it.
As for posting pictures, my advise is to foind some webspace to put them in (your ISP might give you some with your account, or you could by a domain and some space like I have). Upload your pictures there and then when you create a new post you can click on the icon of the picture frame and link the pictures in. You do get a gallery with your AF membership but there's a limit on the size of pictures you can upload, and the number. If you are like me you'll run out very quickly!!!
