Hi
I've figured a method how to insert loading animation to iframe.
Here it is:
First of all download the loading.gif animation:
http://shellytorman.com/wordpress/wp-content/plugins/mygallery/lightbox-old/loading.gif
(I have used Google to find it, but it can be any gif animation)
then edit your fancybox.css file. It should look like this:
div#fancy_overlay {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: #3a3a3a url(loading.gif) no-repeat scroll
50% 50%; /* scroll 50% 50% - centers the image horizontally and
vertically */
display: none;
z-index: 30;
}
Enjoy.

P.S. Do not forget to change the image path.
