DragonByte Favicons is a small but powerful mod that allows you to display favicons for links posted on your forum using the BBCode.
Site icons, or "favicons", are small icons displayed in bookmarks and in your browser's address bar when visiting specific websites. They help identify the site, and is a part of a site's branding. Using this mod, the benefits of this branding will be added to posts, statuses and anywhere else BBCode is parsed.
Using this mod, your users can easily spot whether a piece of text is a link, and get an indication of what website they're about to visit.
