Who needs a favicon, anyway? No one really needs a favicon for their website. A favicon is the little icon you see to the left of a website address in the location bar of your browser; your browser will display a default image if your site doesn’t supply a favicon.
However, you should consider adding a favicon to your site, since visitors who bookmark your site will see the icon saved with the bookmark. This makes your site stand out in their bookmarks and makes it more likely to be visited. Dynamic Drive’s FavIcon Generator makes it easy to create a favicon from an image you supply. Or use favicon.cc to create a favicon completely from scratch.
