# allowsCachingHighQualityImages

A Boolean value that determines whether the image manager prepares high-quality images.

```
var allowsCachingHighQualityImages: Bool { get set }
```

## Discussion

If `true` (the default), the image manager prepares images at high quality. This option produces better images, at a high performance cost.

For faster performance when preparing large numbers of images—such as while the user is scrolling quickly through a collection of thumbnails—set this property to `false`.
