Dal - i think I solved this for him somewhere -
The pull down preview icon menu is a bit more than just a template. It requires that you change a couple of lines in the addpost.php script.
As the javascript pulldown menu (in order to do the preview) has to use the full URL to the icon
https://www.ubbdev.com/forum/images/icon/book.gif rather than just book.gif.
So there's a bit of code in addpost.php that'll trim that back to just book.gif.
