I have a PHP file called index.php. It's a very simple photo gallery page. My problem is that each of my Menu Items has an onclick attribute that sets a different location for images to be retrieved. All the images are on my website hosting server. The idea is when someone clicks on a Menu Item, different images will populate the screen. It's not doing that and I'm not sure why. What am I doing wrong. I'm not real strong with PHP yet. I have attached the file for examination.
