Primos,
Regards Ancestry.com online family trees:
I found out the hard way that if you share (by clicking share) on someone else's Tree's photos or photos of Catholic Church digital records that when that owner of that Tree deletes his/her own Tree, you lose all that data yourself.
It is better to copy/paste those photos into your own "picture file" and then upload them into your own Tree to permanently keep them.
