Here's a demo video (fairly old, have to still update with the latest look): https://www.youtube.com/watch?v=8GfKBvs53Ss
Say you have a picture on a blog post showing a car engine, explaining how to fix something inside of it. You could highlight/link all the individual parts in that car to where your users can buy them on O'Reilly Auto Parts, and make a commission each time they make a purchase (affiliate marketing). I think this type of advertisement is 1) beneficial for users for its informative nature, 2) leads to bloggers being able to focus on content instead of worming offputting advertising into their blogs (such as banner ads), and 3) could lead to a more interactive internet where things in any image can be purchased or even just linked to for informative purposes[1].
