Hello all, I work as part of the IT department for a company that uses half MAC machines and half PC machines. One of our biggest issues has always been compatibility between the two, and so we use Office 2013 for PC and Office 2011 for MAC. Two of our users have recently found themselves unable to use the Insert>Photo option inside of Word 2011. The images in question are not on the local machines but on a Networked server for storage, and when they browse to the file holding the images (Which are in a .jpg format) the images are greyed out and cannot be selected to Insert into the Word document. They have been able to do this before without issue, and this has become an issue since Yesterday, January 12, 2016. (Edit) They are trying to Insert the images into a Header on the document.
