This is a shout-out to a (free) image component on the app exchange. 

A client wanted to be able to see the images associated with an object on its record page - this component did the trick with exactly zero code. 

I'm sharing because it seems like it might be a fairly common use case (displaying student, client, location images for easier recall, etc.)

It also goes under the category of "Yes, Lighting migration can be tricky, but there are perks on the other side!" :)
