This is a nice little trick if you want to open an image or a page for printing in Joomla without having the surrounding template. Instead of having a link pointing at a page like:
Change the link to point at:
Opening it in index2.php just gives you the content without the navigation or other parts of your template. This means you might want to open the link as target=”_blank” so that the user can close the window again afterwards and get back to your main content.
This works in Joomla 1.0 – haven’t tested it in 1.5 yet.
