An Amazon AppStream 2.0 image contains applications that can be streamed to users. The image is used to launch streaming instances that are part of an AppStream 2.0 fleet. All images available to you are listed under the Image Registry section in the AWS Management Console. There are two types of images listed in your image registry that are differentiated by these visibility attributes:
Public Images — Base images that are made available by AWS to help you create images with your own applications.
Private Images — Images that are created and owned by you.
You can use either public or private images to launch an image builder and set up your AppStream 2.0 fleet. For more information, see Tutorial: Using an AppStream 2.0 Image Builder.
You can also delete your private images. Note that a private image cannot be deleted if there are active fleets using it. You must stop all associated fleets before deleting the image.
