Google makes favicons into pngs
One of the commenters at Snipe.Net mentioned that Google has a nice little facility to extract a 16x16 png from the favicon for any website that has a favicon.
You just go to this google address below and input the domain for which you want the png.
So I thought I would pass it around
You will find it here at this address, and just replace 'example.com' with the URL of your choice. google makes favicons into pngs
