I am helping a friend get a book ready for publishing. It uses a lot of images. All of the images were scanned at 600 dpi and inserted using the Insert Picture menu on the Word 2011 application my friend is using. I am using the latest version of Word for Mac as part of my Office 360 subscription. The problem is that while most of the images are more than the 240 dpi the publisher requested, there are about 30 that are coming in at about 100 to 140 dpi (I run a macro I found online to determine resolution). I cannot figure out why some are different than others. My friend as reduced the size of the images to increase dpi, but that only works to a point.

I have been trying to find a way to turn off picture compression. I found this solution:

but it doesn't apply to the Mac versions of Word (i.e., there is no "option" link in the File menu).

I'm going to try saving the file on a colleague's PC and seeing if the solution works. But, short of that, DOES ANYONE HAVE ANY IDEA HOW TO TURN OFF PICTURE COMPRESSION ON RECENT MAC VERSIONS OF WORD?

Thanks for your help.
