Google has launched a new ad format on image search named shoppable ads. It is a test right now where Google will highlight multiple products available for sale within your sponsored ad among Google Images results.
Below is a GIF of it in action:
As you can see, as you scroll through an image you can hover over any sponsored ad with the price tag, and see the items for sale in the image. It will show prices, the brand and much more. Google said they will "continue to roll this out to more categories across more retailers over the next few months."
Google also said in this announcement they are also "bringing Showcase Shopping ads to Google Images as well."
