You can mark images as deprecated to prevent them from being used to create new workspaces.

1. Go to Images and find the image to mark as deprecated.
2. Click Edit.
3. Select the Deprecate this image checkbox.
4. Click Update Image to save your changes.

Users cannot create new workspaces using deprecated images. However, they can continue to use existing workspaces created with the now-deprecated images and edit the resources allocated to that workspace.
