Hello Newcomer,
Thanks for picking that up. I should have looked. This would be the one you mean:

As well as the other photo of a LVG B.I,I suspect the photos with the Tauben are probably as you suggest from that period too.If, and its a big if, the photos are all from the same source, perhaps the photos are taken by an individual who trained with that unit and then served in the Balkans.The only photo where I can definitely identify a unit is a Kasta 5 aircraft :
