How do i make microsoft office picture manager my default to open pictures.

How do I make Microsoft office picture manager my default; it used to be, but now photo gallery has taken over. I open pictures in that program (photo gallery) and ask it to open with Microsoft office and it does, however, it will not save the picture in that program and there is no little box or anything to say open pictures in this program all the time when I right click.  I am not happy that this occurred via an update!!
