broken links or broken page. Help Please!

Hello,
Here it goes. I have made alot of changes to my template. Until today I thought everything was fine. My home page loads, The menus and sideboxes , About Us, Privacy, all categories each load good. When you click on a product you are sent to a mostly blank page. Menu and header at top everything else is missing. I haven't had any sales since Sept. I don't know how long this has been going on. I did contact my CPANEL folks no problems there. I was able to send a feed to Google of my products and noticed the links to the images were wrong today, while fixing that I by mistake clicked on one of my website images and discovered this HUGE problem. Any help would be greatly appreciated. Thanks JIM:cry:
