hmm the images are being resized properly, if you right click on the image, and select open in new tab, it shows the properly sized image.
Using fire bug, it looks like the script is using height: auto on initial load, then changing it to 220px, and 210px just before loading the next image. the slide show script is dynamically playing with the image heights as it runs.
i dont see what in the script is doing that, but fire bug is showing the heights changing.
