Image Swap Offset (Select Swapped Image)

Hello, it would be nice if you could choose which image will be shown on hover. This could work by adding an offset option that allows you to select which of the images inside of your gallery should be shown on top of the featured image. Example: If you set an offset of 3, the third image from your product gallery will be shown on top of the featured image. This could be useful if you want to show specific features that are always sorted the same way in your product gallery. Maybe it would even be possible to select this for each product for even more flexibility or use groups to select multiple images with the same offset setting.
