FamilySearch Wiki talk:Image use
Our Image use policy doesn't officially exclude .doc and .xls files, but if they are uploaded, they could contain macros that could potentially be harmful to users' computers. Additionally, whether they do or not, the page has a warning that tends to scare users away from reviewing those documents.
It is now so easy to publish .pdf versions of these files and we suggest that if someone wants to share info that doesn't belong on a wiki page, that they upload it in .pdf format instead of in .doc or .xls. We propose to make this an official policy on the Image use page.
