+Spec Lite: 'all' visibility image filter
+========================================
+
+:project: glance
+
+:problem: When deployments use community images these community images are
+          not returned when doing an image list.
+          Currently murano and other projects use a property to determine
+          if the image should be used. It is not possible to filter on
+          all images with the specific property. Sahara also shares this
+          issue. Horizon currently also needs to show all images that a
+          user can boot from in the boot intance view and this cannot be
+          done without 2 requests to glance.
+
+:solution: We need to add a new visibility called 'all' which will return
+           all images that are available to the user.
+
+:impacts: None
+
+:how: We will add the ability to list images with visibility='all' to
+      return all images. This will require a bump in the api version.
+
+:alternatives: The other option is to make 2 requests to glance each time
+               you want to list all images or filter by all images which
+               is inefficiant
