Fix cutoff carousel

When first loading or force reloading ircanywhere.com with ctrl + shift + r, the carrousel will load as a single strip and then stretch up but not sideways. Like this:

This is happening because when unslider loads, carousel images have no defined size. Fix was to set size on img so that we have layout defined before loading images.

Starting unslider after a load event would work too, but page would first load the three carousel images on top of each other then suddenly create the carousel. I saw this in chrome and Firefox.
