Image

The Image control displays a non-interactive image to the user. You can use this for purposes such as decorations or icons, and you can change the image from a script to reflect changes in other controls. The control is similar to the Raw Image control, but offers more options for animating the image and accurately filling the control rectangle. However, the Image control requires its Texture to be a Sprite, while the Raw Image can accept any Texture.
