It's an old system (there will be an upgrade soon)
To post a picture:
1. go to 'uploads' (tab at the top)
2. click on the 'browse' button to locate the picture on your computer
3. click 'Submit' and wait a moment for the picture to pop up with a message that the upload was successful.
4. right click on the code next to 'image' : { http://blah, blah, blah...} and copy
5. go back to the post you want to place an image and right-click / paste.

6. click 'preview' because you want to be sure that you didn't accidently copy something that you'd rather not post on a forum...
