MyBB Community Forums

Well I am adding an advertisement to my site with a image that when clicked will go to another page on my forum, could you give me a custom HTML code that I could use (obviously just an example). Thanks!

You can only put that into templates, not posts.

That should be:

<a href="http://www.mybb.com/"><img src="http://mybb.com/images/logo.gif" alt="MyBB" /></a>

This just adds a text link?

No, it adds the mybb.com logo and turns it into a link.
