UI Image

You can create a new UI Image object using Create | UI | Image:

The UI Image object contains the Rect Transform and Canvas Renderer components as well as the Image component.

You can also change the transparency of the image by reducing the alpha value. The Material property allows you to add a material to the image. The Raycast Target property works the same way...
