Changing the favicon
favicon image size is 16px X 16px
favicon file name is favicon.ico and located in the public_html > applications > assets > images > meta folder.
To change to your favicon which appears in the url bar beside the url site name in the web browser winder, you will need to already have an icon prepared ( .png, jpg, gif) before you begin.
Web browsers cannot read the above mentioned list of image extensions so you will need to use an online website fav iconic converter, here is a popular resource: http://www.convertico.com
When you have used the services and you receive the .ico file, you will now need to overwrite the existing favicon.ico file with the new one you received, and don't forget to refresh the page :)
