What is a Favicon?
A favicon, also known as a "favorites icon", "website icon", "page icon" or "urlicon", is an image associated with a particular website or webpage. A web designer can create such an icon, and install it on their domain to give a "uniqueness" to their website. Most of today's browsers such as Internet Explorer, FireFox, and others allow for the display of these icons.
Choose or create the image you'd like as your favorites icon. Be sure to create or choose a small enough image to retain quality. It is also advisable to use a square image, so the image is not skewed when reduced to the 16x16 icon.
Click the "Browse" button, and find the image you've chosen to use for your favorites icon. Select that image and click "OK". Your almost done!
Click the "Create Favicon" button, and follow the download and usage instructions. That's it, you're done!
