The image is genuinely missing even in firefox. This seems to be a problem with your theme or the wp-e-commerce plugin the image source should be pointing to http://www.beewellmassage.com/wp-content/plugins/wp-e-commerce/wpsc-theme/wpsc-images/cart.png
If you look at the HTML source code there’s some weird base64 code in there. Your images should only need an img tag. Not sure why your theme is using such a strange img link. I would check your theme file and see how these images are being pulled in.
