I presume that you are talking about a having a choice of the order of Album photos, not individual profile photos.
I went to see what choice there was in my Albums - I did not alter it... but I noticed that if you select names that the photos get ordered by the individual Names attached to the photos, not by the Title names of the photos... See for example in my DNA Photo Album attached.
Obviously if I add an Tree relating to the MONCKTON Family, I was not expecting to see it in first position of all the DNA Trees, but the fact that I have attached EDITH ALFORD to it has resulted in it coming First, before eg. the COOPER DNA Tree - which ends up on Page 4 of the DNA Album. Oh what a mixed up mess!
I noticed that all photos without names (that I have used for Stories) can be ordered by their Titles... I decided to number 6 that are attached to a DNA Story and that has kept them to the top and keeps them in order on the story they are attached to. So that's not bad.
But the issue of dated photographs is not going away and for that reason I have given up now on this photo issue. It has become very complicated and very annoying when you are trying to give supremacy to clear images of genealogy matters like DNA Trees and Tree Charts and DNA Matches which do not require dates and can have many relevant names attached to them. Sadly the photos giving the detailed DNA Match information are not showing at all at the moment - See this link...
DNA Match details between Lucy & Katherine A Hand nee. Fernandez ...With Fernandez, Katherine A & Rumble, Lucy
That image shows the fact that Amount of Shared DNA between my granddaughter and a new cousin, Kathy, we recently met through Ancestry DNA is:
56 centimorgans shared across 4 DNA segments.
This image is no longer alongside the relevant Treeand when you want to see the details in the image - they are not accessible now at all! So I suppose I will now have to go over all the profiles and type out all that information so people can see it! I have no time to do this.
Also see that 2nd link below to the attached missing image! As I say - the changes that have happened have brought about some very undesirable effects to my Profile Photos - many are not visible, if you want to see genealogical facts & details. I give up!
I am happy for those that are happy with their ordered Family pictures though - genuinely.
