If you’ve ever had a client ask for one of those little icons that show up in the browser title bar, you might try Favikon. It’s a really easy way to create favicons from a gif, jpg, or png file. You can see the one in the title bar I just created. The nice thing about favikon (over some of the other favicon services I’ve seen) is that you can crop an image to just the portion you want. Makes it easy to grab a portion of a logo or design without firing up Photoshop.
