1 - SRP images as part of the pack, forming one product image
In this option, the SRP image is actually part of the whole set on the shelf, meaning that the image clickable on the shelf is the group of products contained in that one set of SRP.
2 - SRP images as a separate element
This option is a bit more work, as we need to separate the SRP from the products, this means that when the respondent clicks on a product on the shelf, it is clicked on as a separate unit. This allows for a more granular approach. Also, means the experience is closer to what it is in real life.
