Which object is used to add graphics to a page or popup in the GUI Designer?

The Image Control is the correct choice for adding graphics to a page or popup in the GUI Designer. This control is specifically designed to display images, allowing users to incorporate visual elements such as logos, icons, or backgrounds to enhance the user interface. The functionality of the Image Control includes options for adjusting the size, positioning, and alignment of the image, making it versatile for different design needs.

In contrast, Text Control is primarily used for displaying text, which means it does not support graphics. The Button Control facilitates user interaction by allowing users to trigger actions, but it does not display images in the way that an Image Control does. Lastly, the Video Control is intended for displaying video content rather than static images, further highlighting the distinct purpose of the Image Control within the GUI Designer.
