Hi Support and @MikeTO,
On my master page, I have picture frames that are facing each other: one is standard, the other one is flipped. I apply this Master to a page and drag the same picture in both frames: the first remains untouched and the second is flipped. Then I choose "Apply Master" and all the sudden the initially flipped picture returns unflipped.
So to answer your question: it is the picture frame on the Master that is flipped. Not the image.
If I understand properly your comments this means the "flip" operation is reapplied to the image each time the master is reapplied:
1) apply: image is flipped
2) apply: flipped image is flipped -> no longer flipped
3) apply: image is flipped again -> flipped and so on
If this is the expected behaviour from Publisher, this is very disturbing. However I doubt it is the case. By the way, if the image in frame on the page (not the master) was resized before, reapplying the Maser will reset the resizing as well.
This issue was already reported with V1
Got it, thanks @MikeTO and @DrM0lek,
I was getting Déjà vu when I initially read this but I wasn't 100% sure, I've confirmed we do have this issue logged currently with the developers and I've added this report for consideration.
