Photos layout questions

Hi Booking team,

I've noticed in some partners, that they have different picture layout, when opened in booking.com. Example is one picture attached (I've covered the picture with blanks due to copyright).

When the property is opened, there are several smaller photos and one bigger photo which probably is the main photo. And all these smaller photos are hyperlinks to the actual photo.

How Can I do this for my property? Currently when my property is opened in booking, the main photo is shown...

Thanks for the help!

Kind regards
