Your problem has nothing to do with NoScript. I just blocked both amazon.com and images-amazon.com with NoScript, disabled acceptance of all cookies, went to the exact pages you are describing, and everything still displays correctly. The broken graphic icons in the image you uploaded indicate something else wrong, usually, a lack of memory. I would clear all private data (except for saved passwords), close the browser, and re-start it again.
How large is your FF disk cache? If you set it to 100MB or more, it can cause problems after while. Keep it to 75MB or less.
