Using images in your watch face can really help bring it to life, from a full-screen background image to individual detail images to add interest.

Place your image resources in the`res/drawable`folder, for example`res/drawable/face.png`, and then reference the image as follows:  

    <PartImage x="100" y="100" width="250" height="250">
      <Image resource="face"/>
    </PartImage>

The`PartImage`element, as with other containers in Watch Face Format, can be modified in many ways, including being scaled, rotated, transformed, tinted, or masked. See the[`PartImage`](https://developer.android.com/training/wearables/wff/group/part/image/part-image)reference for more information.

### Vary the background

One effect that can provide interest is to change the background every hour. This can be achieved through the use of the`Images`element, for example:  

    <PartImage ...>
      <Images change="ON_NEXT_HOUR">
        <Image resource="background1"/>
        <Image resource="background2"/>
        ...
      </Images>
    </PartImage>
