Problem with Slider Images

First... I love this theme! Now.. I am having an issue where upon initial load, my front page slider images only load partially. About 15% of the image displays vertically and then the rest of the page loads. You can see the images changing, but you still only see about 15% of the image. When I reload the page, that usually solves the issue. This problem happens for me more than 50% of the time upon initial load of the page (with a clean browser cache). I've sized the jpgs to 1200x514 at 72ppi. This happens for me in firefox and IE. Website is www.pointnemo.pn Help!!! Thanks Brandon
