FindAGrave is a neat site and makes it easier for genealogists to locate burial information.
One suggestion if you are taking pictures for a memorial on FindaGrave:
Get some perspective
Include an image or two showing the relative position of nearby stones. Consider labeling who those stones are in the photograph and indicating which stone in the picture is actually for the deceased person in whose memorial you posted it
The relative position of stones can be helpful in determining who may be related.
Not every adjacent burial is a relative, but sometimes they are.
