The main image, as well as the more views images shift upon selecting the right swatch. Click blue, L, for example, and you get the corresponding set of images. You can set the sizes you have on stock differently for each color. This means that depending on the selection of the first attribute option ( color ) second attribute options ( size ) change. This is one of the core Magento's functionality of configurable products, and our extension fully supports it. For full features listed, visit Color Swatch for Magento page on our website.
