A few contributors have discovered the easy way to send a photo or document -- just compose a mail to
update3@lockegenealogy.org, attach the photo, and identify the ancestor in the subject line. Note that you should give name + birthdate, or LockeID. (Unfortunately, the "person ID" on the web pages changes with each update.)
I received 27 photos this way on Wednesday! It turns out, to my surprise, that it is actually easier to deal with photos one ancestor per message.
