I really need someone's help on this> I have a little image inside an IFrame that upon being clicked on, will display another image and slide down a little. How can I make the IFrame automatically get bigger or smaller, according to its contents?

Thank you so much!

\***edit**
After researching this more, I have found quite a few examples that claim (i have not tested them) to do what I need, but ONLY after a page-refresh. Which is something I cannot do.
