RocReadaR : Release Media To Public
This feature is fairly simple. The basic idea is to hide media that hasn't been published yet by the publisher.
On the Issue Page page, add a checkbox for "Published" or "Released to Public". When the page is saved, save that as a new field in loopback as "ReleaseToPublic".
When image recognition occurs, only include pages marked as "ReleaseToPublic"
Alternate version - Release Date
Add a checkbox and a DateTime picker. Save the field as "ReleaseToPublicDate"
When image recognition occurs, only include pages with "ReleaseToPublicDate" field as NULL or in the past (ReleaseToPublicDate < new Date())
