VO-wide image lists are accessible to authenticated users from the AppDB VMCaster web interface, under
where [VONAME] must be replaced with the name of the VO in question. To access them without a browser session, users must create a personal access token in their AppDB profile page, which they may then use instead of logging in, using Basic OAuth Authentication
where [TOKEN] must be replace with the actual access token.
