I've had a search around and am struggling to get to grips with this template business (new to Xcart). I'm trying to change xlogo.gif to xlogo.jpg but I can't do it in head.tpl or customer/head.tpl. It just comes back with File Operation is Failed and reverts the image to xlogo.gif

I'm guessing I'm changing it in the wrong place? Apologies if this is a stupid question, I am trying to learn as much as poss from searching but can't see an answer to this one.
