Hey! I have on my homepage several iFrames right now, and above each iFrame is an "reload"-button for that frame.
<INPUT TYPE="image" src="refresh.jpg" onClick="frame1.location.r
<iframe src="frame1.php" name="frame1" frameborder="0" width="370" height="95" scrolling="no">Your browser doesn't support iFrames.</iframe>
But there is some problems with that. The reload-button asks this "[To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier?]" when trying to reload my php when an user has changed it. It should still be able to reload properply without asking that.
And second of all, my iFrames can't autoresize depending on its content.
I have looked at http://www.prototypejs.org/
