How do I post more than one pic in a thread?

You will have to find a webhost for your pictures like Cartogra etc and use the IMG button when posting. The software won't let you attach more than one photo per post.

If you use the attach file section with the browse button below when posting a picture- you can only do one picture at a time.

But if you use the IMG button the pictures has to be on the Internet and you can post how ever many you want.
You just click the IMG button- put the url in the box that pops up and click ok and repeat that for every picture you want to post.
