I recently downloaded Windows Photo Gallery onto my computer with Windows 8.1.    Today I downloaded pictures from my Samsung S5 phone into the Windows Photo Gallery.  They seem to be displaying just fine.   However, when I attempt to email them using the Share function, I receive a dialog box that says that these pictures are not able to be resized for emailing.  I can't possibly email them full size.  Why can't these pictures downloaded from my Samsung S5 be resized for emailing in Windows Photo Gallery?
