You can nominate 'Signage Administrators' which will be able to not just see the images they upload, but, also the images that all users upload at your school.
In order to nominate a 'Signage Administrator', at this time, you need to send the ID Number of the users that need to be an administrator to: hsn-helpdesk@schools.vic.edu.au
We are currently working on automating this process, however, for now, it is a quick manual process.
