iframe help

I think I've finally figured out the iframe stuff (thanks to some of you guys). One thing I can't figure out though is how to have an image be in the iframe when the page loads. Right now it just shows a "page cannot be displayed" message until you click on one of the links. How do I get an image to be there before clicking on the links?

Thanks for the help.

did you point to a page? for example, do you have (the code you have might vary)
[php][/PHP]or do you have [PHP]
