I don't know if there is a way to do that with Zazzle.
One way, if you have the graphics abilities, would be to take a "screenshot" of the full "add to cart" page for a specific design and just crop out the picture of the design on the t-shirt and size it down for your needs.
You can try right clicking on the image on the add to cart page to see if it will save to your computer as well.
