Do you have a favicon at your blog? What is a favicon? When you bookmark a page, a logo is always “attached” to the title of the page. That’s the favicon. Major sites like Youtube and Google have them, and I just added one for NextTutor too!
If you would like a favicon, you can check out this url.
A little thing to note though. This tutorial is for photoshop users. Non photoshop users can Google Favicon. You also need your own webspace because you have to upload a file up and link it from your website html code.
