Thanks for the tips. I succeeded with the tip for FireFox.
But adding the line for IExplorer, did not show the favicon in IE8.
Furthermore, the favicon in FF disappeared upon page refresh (F5).

Here are a copy of the content in my <head> placeholder;
<link rel="icon" type="image/png" href="teeeest_htm_files/LogTest.png" />
<link rel="icon" href="href="teeeest_htm_files/LogTest.png" type="image/x-icon">

Will appreciate any help.
