Crashing in Chrome when viewing page in lightbox

I am loading a very simple page template into Lightbox. It just shows the image, the title and description.

After clicking three or four times in Chrome, the browser crashes.

Also, sometimes the lightbox loads nice and large. Other times it loads in a small, cramped box.
