David Riecks, leader of the Photo Metadata Project

has a post over on The Library of Congress website about the subject of

Social Media Networks Stripping Data from Your Digital Photos

This is worth reading, if you care about your images.

Why should you care about this is explained in the article on what social media sites do for who does what check out this site www.embeddedmetadata.org

Data stripping is something that we need to really care about as it aids in more ways than (as the article explains) just keeping our names in images. I am embarking on a social documentary project and it will be really important to the ethics of the project that the metadata in the images is retained with the images. If the people photographed in the images are not identified correctly that becomes a problem, it should be up to the photographer what gets revealed not up to the discretion of the social media networks to decide for us so this ultimately becomes a freedom of speech issue.

Data stripping on Social Media Networks with your digital images is therefore not in our interests.
