To deactivate the vote button go to settings > general and uncheck “Activate voting”.
Currently you can’t add the “add to cart” button at the bottom of the image, it only shows in the lightbox when the user click on the image.
You could add this line of code to the styles.css file in the theme but you still need to write javascript to make the order form show up.
.img-metadata a.box-add-to-cart {
display: inline;
}
