I'm all for shoving a .php ending on it, PHP is much more reliable and stable in Mozzilla/Firefox and Oprea when it comes to including files. Personal opinion though

What was the other thing Oh yes, what do you mean resizing the borders? I've got it running in Firefox and it seems fine to me, unless you mean the text getting very close to the border, but that can't be helped at the current time. Although I will try and fix it by reducing some image sizes
