```

## HouseLayoutFinder.GetImages
```pascal
function THouseLayoutFinder.GetImages(room: EHouseRoom): TImageArray;
```
Retrieves the images for a specific `room`, as the {ref}`House Viewer` draws them.
This returns a `TImageArray` with 4 images, one for each possible rotation.
`EHouseRoom.UNKNOWN` has no image and returns an empty array.

The images are read from the game cache the first time a room is asked for and kept in memory
after that. The house viewer picks each room's image from an enum keyed by the room's type,
which is not the same as its {ref}`EHouseRoom` value.

Example:
```pascal
img := HouseLayoutFinder.GetImage(EHouseRoom.ACHIEVEMENT_GALLERY)[0];
img.Show();
```

## HouseLayoutFinder variable
