Why are my stock photos not displaying as stock photos in VinMotion?

If a stock photo is input into our system via a process other than the stock photo processor (for instance a Batch Photo Import or based on photo urls from a polling file) then VinMotion will not label the photo as a stock photo. This could also affect Photo Reports. Another possibility is if there is an edit made to the photos after they are added (like an overlay rule or Clipping).
