You should be able to get away with just placing it as "favicon.ico" in the index directory. This works for a lot of host`s or this sometimes works for me
"<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />"
in the header part of the index page, I often copy it to all the pages to make sure It`s got from all angles.
Im prolly teaching you to suck eggs but at least anyone who wants to know how it works now does.
