# Adding the VisionPro Displays

On a Page, the VisionPro Display is used to display images output by a Camera Device or Image File Device, or an image output by a VisionPro Tool Block. In this example, a VisionPro Display will be configured to display images output by an Image File Device, and another VisionPro Display will be configured to display the output of a rectangular region.

2. Click the grey dot beside the Subject property to launch the Expression Builder.
3. Press the Add Tag button and navigate to the Image File Device, where the Image tag will be selected. Press the Accept button.
4. Next, add another VisionPro Display to the Page, and configure the Subject property to the outputImage tag.
