I have yet to figure out how to save the original icon file.
However I found a better way a (although tedious)
You simply save the logo of the website you want or any photo you want to represent as an icon.
Then upload it here
and then download the new icon.
and you now have that photo in an icon format.
Then just right click the link in the quick launch bar >>>Properties>>Web Document (tab)>>change icon>>browse to new file>>apply
I like this way better. Now I can use whatever as my icon to identify each site I use alot.
Mostly woirking on my website and editing photos etc. I have links to my site, image shack, sitemeter etc.
Makes formatting and building easy.
