how do I change the photo that displays next to my own name?
Welcome to the "Commmunity.FamilySearch" Forum.
I am just another 'lowly' User/Patron ...
Of course ...
Providing your are referring to Your 'FamilySearch' Account (and, NOT this "Community.FamilySearch" Forum) ...
You need to access your OWN (personal) profile, in "Family Tree", of 'FamilySearch'; and, depending on the circumstance, either:
(1) Add a NEW "Photograph", in the "Memories"; and, then, once processed, use that NEW "Photograph"; as, your "Portrait"
.... Once the NEW "Photograph" is processed; then, use the "Portrait" feature/function/facility,
.... to "Change" your "Portrait";
(2) Go straight to the "Portrait" feature/function/facility, select "Replace"; and, then, select either:
(a) Upload Photo; or
(b) Select from Gallery
to "Change" your "Portrait".
Here are some "Knowledge Articles", in 'FamilySearch":
I hope that this may help/assist, somewhat.
Is this where you wish to change your photo?
