What is favicon? and How can I use it?
Its an image displayed next to your Address bar of browser. you can refer http://en.wikipedia.org/wiki/Favicon
Many times developers are complaining, image is getting displayed properly in Mozila but not in IE.
To get it displayed in IE you need to do proper formatting of image, Mozila is capable of rendering all types of images.
you can also use animated images.
If you are facing any problem, I would like to suggest use online favicon generator http://www.html-kit.com/favicon.
Download generated favicon using above URL.
<link rel="icon" type="image/vnd.microsoft.icon" href="http://example.com/image.ico">
<link rel="icon" type="image/png" href="http://example.com/image.png">
<link rel="icon" type="image/gif" href="http://example.com/image.gif">
You can put the favicon.ico in the root folder of your application.
Here is HTML syntax that you need to add in your Head scetion of Page.
Additionally, such icon files should be either 16×16 or 32×32 pixels in size, and either 8-bit or 24-bit in
color depth (note that GIF files have a limited, 256 color palette entries). Firefox can display animated GIFs
and (starting with version 3) APNGs as icons.
