HI buyscripts,
Thank you for you fast answer (less then 5 minutes).
For Firefox the problem is solve i can see my favicon from the user and admin view.

For those who want to add favicon, you just have to create a picture on photoshop and give i'm the name your want with the extension .ico Upload it to public_html and add this code :

<link rel="shortcut icon" href="http://yourwebsite.com/thenameofyourfaviconhere.ico"/>

The spot for user interface view is :
Add this code on page template/header.tpl.

The spot for admin interface view is :
template/admin/main.tpl/

I still not solve yet my problem, so i can see my favicon on Internet Explorer.
As soon i have the real good code i will post it on this message.

Anybody have the code for favicon to appear on IE ?

Thanks again Buyscripts.

regards,
General Dee
