Image Button in Canvas App

To create an image button in a Canvas app in Power Apps, you can follow these steps:

1. Add a new button control to your canvas app by going to the Insert tab in the ribbon and selecting Button.
   
2. Select the button control and open the Property pane by clicking on the Properties icon in the right-hand pane.
   
3. In the Property pane, scroll down to the Image property and click the ellipsis (…) button to open the Image dialog.
   
4. In the Image dialog, you can either choose an image from the built-in icons or upload a custom image. To upload a custom image, click the Upload button and select the image file from your computer.
   
5. Once you have selected your image, click the OK button to close the Image dialog.
   
6. You can also customize other properties of the button, such as the OnSelect property (what happens when the button is clicked), the HoverFill property (the color of the button when the user hovers over it), and the Size property (the size of the button).
   
7. Save and publish your app to see the image button in action.
   

Note: The image button will only display in the Canvas app player, and not in the Power Apps Studio design environment.
