wp ecommerce format problems

I just uploaded wp ecommerce and tried adding a product with an image. Then added it to a page, but when I view it, it cuts off the top and bottom of the image. It also sort of squashes it to the left a little from what it looked like in the wp ecommerce preview… like it’s making room for the writing on the right. In the plugin preview the writing went over the boundry of the theme so when I added it to the page, it automatically reformatted a bit, which is when I got the squashed image. But in the page view and the plugin view, the quantity option, price and buy button are all spaced odd and messy looking, too. Any ideas how to fix it? The page is:

Any help is greatly appreciated!
