[jQuery] JCarousel: flexi height images in vertical carousel

[theneemies]

We're using JCarousel on http://neemtree.com.au, and ended up with a
JQuery workaround for setting the heights (view source). On FF2, when
the page is first loaded, images are 'squished' together at a height
of ~10px, reloading the page resolves this. Could someone take a look
at it and respond if they see something obvious/have a suggestion for
handling varied height images.
