Oh my these are beautiful.
You can post more than 3 pictures in a topic. After you have posted your 3 pictures look at the bottom of your post, there is a button that says add new attachment. Click that button and you will get the little windows for attaching your picture files. Just keep doing that one at a time. You can keep adding them for up to an hour. Then if you time out and still have more pictures just reply to your own topic with more picures. Like I did here:
