So this is how you're able to navigate through different pages without having to visually reload the images on the left? I assume when a link is pressed the next page (include the sidebar) preloads and then appears so there's the illusion that nothing changed on the left side.
I've tried to make something like this before but whenever I would press a link, the entire page is emptied momentarily and the new page is loaded (just like loading any new page in a browser). I want the sidebar to stay visible the whole time while the new page loads.
Does that make sense? I don't want to get the feeling that you're starting from scratch every time you click a link.
