Show Iframe on Google sites

Google Sites blocks IFRAME tags, JavaScript scripts, some DIV tags, and other essential XHTML elements that Google considers "unsafe." This post shows a way to get around it.

To show an IFRAME, thus bypassing security restrictions in Google Sites, simply add this magical line to your IFRAME tag:

igsrc = 'http://www.google.com/ig/images/no_image/no_image_gadget_thm.png'
class='igm'

This will fool Google into thinking that you are inserting a Gadget, even though you are actually inserting your IFRAME. ;)
