jQuery jCarouselLite, or its jQuery UI counterpart, not showing up on page load

The problem: 
A jQuery jCarouselLite or jQuery UI Carousel appears to not show on an initial page load, but does show up on subsequent page loads.

The solution:
Give image elements inside the carousel list items their width and height through attributes or css.

The reason:
I assume this is to do with the carousel running on 'document.ready' and not knowing the dimensions of images inside the carousel and therefore applying a 0x0 size to the carousel.  It works on subsequent page loads because the images are cached and their sizes known.
