It would be nice to be able to remove the select box (or radio list) if you use variant images as it would be a much more elegant looking solution. It seems redundant to have both the image and the select box. Does anyone know to remove the select box?
Found an easy fix:
in skins/basic/customer/views/products/components/product_options.tpl
change:
{if ($po.disabled || $disabled) && !$po.not_required}{/if}
to
{if ($po.disabled || $disabled) && !$po.not_required}{/if}
