I knew that I would find something, if I was my persistent usual self ...
Here are some other "Knowledge Articles" in 'FamilySearch':
How many memories (photos, stories, documents, and audio files) can I upload?
Published: 20 April 2020
Where it states:
If you contribute many photos, stories, documents, and audio files to FamilySearch, your gallery can become so full that is difficult to manage. If you have finished tagging the memories and titles, descriptions, event dates and places, and other information, you can move the image to your archive to declutter your gallery.
When you archive memories, they remain online for others to see. If you have tagged them to a person in Family Tree, the tag remains, and other users can still see the memories. The only thing that changes is that you no longer see the memory in your gallery.
When you view your archive, you can see the memory, edit it, add it to albums, share it, and do all of the other things you could do from within your gallery. You can also move it back to your gallery.
And, here is an interesting article on the 'Data Limits' for individuals/persons in "Family Tree" of 'FamilySearch'.
What are the data limits on about people in Family Tree?
In Family Tree, the record for a person has the following data limits:
• Spouses: 200
• Parents: 100
• Children: 400
• Names, facts, and events in the Other Information section: 200
• Sources: 200
• Memories: 1,000
• Other persons identified as "not a match": 400
• Discussions: 50
• Individual notes: 50 (each note can have up to 10,752 characters)
• Relationship notes: 12 (each note can have up to 10,752 characters)
Certainly good to know ...
I hope this really helps.
1,000 is the max that you can hook to one specific person
but at the gallery level (the number of items at the account level) there really is no limit - - I have gone as high as 20,000 testing the limits. After you get to about 12,000 the system really slows down though.
At the album level - though there technically is no limit - the effective limit is also 1,000 because after that even if you load more - you wont be able to see them if you display the contents of the album.
I cannot find a quick answer to your question ...
That said ...
I did find this "Knowledge Article" in 'FamilySearch':
My gallery in Memories is too full
I hope this helps, just a little.
ps: I am not even sure if there is a 'limit', I could not find any reference to such anywhere.
