im looking for exactly the same thing, the add to cart button under each image instead of the select button,
i have placed the add to cart button under the images by changing the css and making it inline instead of none and it works perfectly
the only problem is the options when you press the add to cart button come up under all the images but what’s wierder is if you close it and ress again it coms yup on the top left of the screen and cannot be removed without refreshing the page
i see about changhing the javascript but cannot find that reference anywhere in the jquery.js file
the normal add to cart button at the top of the page woorks perfectly, but the one adds to the bottom of the images does not
if you can help that would be great
thank you
