You added the photos to a burial unknown. It has been merged. The exact photos were on the original memorial and dated 2007 (yours are 2013). You should REMOVE all photos you copied that you did not take yourself. You should never copy photos from other memorials, to do so is a copyright violation.
Can I add a photo that I found on Find a Grave or on a different website? No. Do not add photos to Find A Grave that you have acquired from another memorial or from another source. Similarly, do not add screen shots from other websites or scans of obituaries or newspaper articles (11/29/12). Photos fall under copyright protection laws, even photographs used in obituaries. In general, if you did not take the photo yourself, you should not post it. The only exceptions to this are photos that are old enough to have fallen into the public domain and photos for which you have received written consent from the copyright holder.
FYI, you should also not add photos to burial unknowns, only to those memorials with known final disposition. Thanks, Jen
