One of my use cases for search is product exploration. Especially when it comes to physical goods, image search sometimes is the only way to find a supplier. E.g. looking for a specific configuration of cabinets or planters with big castors etc. While I can limit the web results to my country of choice, I cannot do so with the image search. Technically I get what I'm looking for but from suppliers in the other hemisphere ¯_(ツ)_/¯
Adapt the same workflow as in the web search: a user would be able to narrow down image resutls from the web properties that would've been suggested in the web search.
