There are three ways to assign a room type to a photo:
1. Click on a photo in your image library, and then choose the room type from the pop-up window.
2. Click on the drop-down arrow at the bottom of the photo to assign a room type.
3. You can also assign room types to multiple photos at the same time by ticking the boxes in the upper left-hand corner of the photos, and then click on the "Assign room type" button above the main image.
