Just an FYI:

At the bottom of the page (and my post) is a link to the Test forum where you can find and practice posting multiple pictures within a single post by using the img html tag. Even if this is a bit difficult, you can 'respond' to your own posts to keep the pictures within the same thread instead of posted across multiple threads.

Here is a link that might be useful: Test Forums
