thanks
I'd tried that and it hadn't worked and I've just tried it again and it works .....!!
But now I have another problem - the images in the "incl_header.php" file won't load because it's now at a different level
when incl_header.php is included into a page at the root, the images load in because the relative directory path "images/image.jpg" works
but now the incl_header.php is included in a page in a sub-directory I would have to put "../iimages/image.jpg" for the images to be loaded - arg !
How can i get round this problem ? - do i have to use an absolute file path for all images ?
