DO NOT "Panic" ...
'All is NOT Lost' ...
Here are some "Knowledge Articles" in 'FamilySearch':
Why isn't my photo or document uploaded yet?
Why does it say that my photo is restricted?
Where it states, among other things:
FamilySearch uses software to review each memory item that is uploaded to ensure that it complies with our rules and guidelines.
When a memory item appears to violate the rules and guidelines, FamilySearch takes these actions:
You can review the case and respond if you feel the memory item should not be restricted.
As has already been proffered by, 'Cindy Hecker'; and, 'A van Helsdingen' ...
Simply, REQUEST a REVIEW of the "Restriction" ... you have x30 Days to do so.
In many cases, the "Restriction is lifted, sometimes it is not.
As as aside ...
Please be aware that "Family Tree" of 'FamilySearch' is used in MANY Countries and Unions ALL around the World, by many Users/Patrons from those various Countries and Unions.
As such ...
'FamilySearch' MUST, consider the MANY "Standards" of 'Culture', in the various Countries and Unions, not just the "Standard" of (so called) 'Western' Culture.
Just my thoughts.
The sponsor of FamilySearch, the Church of Jesus Christ of Latter Day Saints, has set strict rules about what photos can be uploaded. Many of these rules are due to their religious doctrines and beliefs. Several of these rules are often criticised by FamilySearch Users, in particular the bans on kissing (even wedding photos) and any sort of religious dress from any religion, and the need to get permission to upload photos of fishing, hunting and those with commercial logos in the background (e.g. a shop front). More broadly, I would criticize the rules for leading to a "sanitized" view of family history.
The rules are here: https://www.churchofjesuschrist.org/legal/familysearch-upload-guidelines-and-policies?lang=eng
You should contact FamilySearch Support and ask that the photo is either approved for upload, or that they specify which of the 15 rules they believe has breached by your photo.
Initially photos are scanned by a computer not a real person so it is worth replying to the email and asking about your specific photo. Computers are not perfect and it may need a live person's eyes to review it.
as has been stated - the initial restriction is not done by a human being - but some AI process - that sometimes gets things wrong
simply reply to the email and say "restricted in error" and 9 times out of ten it will be unrestricted.
