You don't need any Java, really. You can use DHTML to open up a new "full screen" window, and then display any html page within it to do the slideshow. I've gotten this to work, but I am having trouble integrating it into the complex php environment of cpg.
Here's an HTML page with code that opens up a full screen window with no menu, or nav bars. This is linked to a button named "slideshow" and will attempt to display the contents of the file 'do_slide_show.htm' The do_slide_show page would loop through the images, and include the "stop slideshow" button which merely has to close its own window.
Any one else care to contribute the do_slide_show page?
