Foxy,
I just pasted my last post from the A2K FAQ.
Essentially what you need to do to post an image is this:
Find the image at a website. (ie.
http://www.google.ca/intl/en_ca/images/logo.gif )
Then when you're entering your post you click on the "IMG" button and it will ask you for the image URL.
So you paste the image url into the box "http://www.google.ca/intl/en_ca/images/logo.gif" and click okay.
In your posting box it will look like this:
Code:[IMG]http://www.google.ca/intl/en_ca/images/logo.gif[/IMG]
Preview it and then click submit and you'll have a picture in the thread.
Try it using the image url that I just included there.
Do that make any sense?
