Ok then, I did some further testing:
1. prepared two pictures, 1 jpeg 1 png
2. added one address entry with the jpeg contact photo
3. added one address entry with png contact photo
client was CardDAVMate 0.13.1
browser was Firefox 43.0
for the jpeg dataset:
[many more lines to follow here]
for the png dataset:
[may more lines to follow here...]
Both vcf files have almost the same size.
So CardDAVMate seems to convert the jpeg picture into png. So far so
good. Unfortunately, some other clients do not show up the pictures in
the address book after syncing. E.g. android smart phone with
carddavsync and thunderbird with SOGo Connector. Both clients worked
fine until some weeks (months?) ago. In CardDAVMate both pictures show
up just fine!

So it says it's a JPEG, but it is really a PNG.
When I edit this entry (leave the contact photo
What client? If CardDAVMate, what browser?
this is what happens to the photo:
The photo contents looks unmodified, but now it is (correctly!) registered
as a PNG.
But I assume the photo does not get lost, as it is in my case?
