They have recently installed a customized Lexmark multifunction product (MFPs) which quickly scan photos or significant documents and transfer them online to your personal genealogical space. The scanning system produces high-quality digital images in both .jpg and .png file formats and will accommodate up to 5 MB in size. Items may also be scanned and saved to a thumb drive, all FREE of charge.
You can then identify people in the photos and connect them to respective ancestors in your FamilySearch Family Tree, and you can post links and share the information with other family members and encourage them to share as well.
