About Images
You can use an image as an underlay for creating geometry. You can import an image onto a datum plane or a planar surface. You can reference and use images to model a part.
When you import images, they are not added to the Model Tree. No feature is created.
You can only work with images when the Images tab is open, but you can display images in the general application.
