I don't think I'm using iCloud (don't flame me, please - I am not a newbie, but I am an old mistrusting "oldbie"). I'm using Monterrey 12.7.5 on my Mac. Phone iOS is 17.6.1
This screenshot is from my downloads folder.
There is only one image in each file folder - a single, normal image file. Sometimes jpeg, sometimes HEIC.
I did request "all photos data". These images were from a vacation, and I usually transfer my pictures soon enough afterward so that the dates are close to the originals, so I didn't bother with all photos data. This time, it was from awhile ago, so I wanted the data included so that I could date them better. Very few of them had been edited in any way before air-dropping them
I just tried again with a single picture instead of multiples. If I requested all photos data, it came within a file folder. If no data included, it came through fine. So I guess that's the problem.
I like keeping the pictures in special vacation file folders, but if this putting them in Photos is the only way to do it simply, I'll have to do it. I've not used Image Capture before, but I may have to try that too. You'd think that with all the advancements Apple has made, they would have made that whole process a bit more transparent. I love Airdrop for its simplicity - but I guess it has its issues - any least when it comes to the data part. sigh.....
Thank you all for your your input. At least I understand a tad better and have something else to try now.
