Thanks for confirming this — it’s helpful (if a little disappointing) to know that there isn’t currently a clean way to append new images directly into a published OID service. Rebuilding a connection in apps every time we need to republish isn’t ideal, especially when we’re just trying to add a handful of new photos. Unfortunately, I also don’t have the option to make my imagery web-accessible, so the “append with URLs” approach doesn’t work in my case either.
I think this workflow would really benefit from some improvement. It would be great if Oriented Imagery datasets supported an update/append option similar to how hosted feature layers can be overwritten without changing the Item ID. That would save a lot of time and keep downstream apps and maps stable.
