Which photo source can replace existing photos?

Basically, any photos at the same "level" can replace photos of that level (or below). This is generally the hierarchy of photos (there are occasional odd situations or minor ways around these things): VinMotion photos of type 1 - Always replace anything else. RapidLot photos - Replace anything here or below. There is a way for VinMotion photos to "release control" to RapidLot so that RapidLot photos can replace VinMotion photos, but that is a special circumstance. Polling photos (include from Polling itself and 3rd party photos like VINReal) - Replace anything here or below. VinMotion photos of type 4 (Temporary) - Never replace any actual photos from the sources above, only replace photo types listed below. Stock photos - Can only replace other stock photos or the placeholder photos. Note that we do not currently have a "proper" stock photo provider, but we do have a limited set of images that can go on some vehicles. Placeholder photos - These are the lowest and can only be applied if there are no photos on the vehicle. They are some version of "Photo Coming Soon" Because of the nature of how Polling and the 3PMT system batch processes things, we sometimes have checks for whether we have loaded particular photos. So, there are occasional times when these photos do need to be removed in order to be replaced.
