Look in the formatting section above.
To put multiple images on the same post you put the [pic......... in the "message section". Do not put anything in the optional URL section. So when you are ready to post you will see 2 lines in this message seciton that start with [pic....
If you don't put a new line between the text you will get both on the same line side by side like below. I put a "center" command before the pics.

Hope this helps
