I have an online art gallery at www.littleyellowhorses.com which uses the Couture theme. As you can see, when you select a product you can select from a drop down for either a black or white frame. Ideally I would like the main product image to then be shown with either a black or white border to replicate the finished product.
For some reason the product images aren't working quite like they ought to on my theme. Whenever I upload a second image for a given product they come up small - and cannot be seen too well, so I'm happy to review the whole way I show the product images... ideas welcomed.
