I got the trial version, and see that the wordFragments fix the issue where a generic image can be inserted into a word document and is visible to Mac users.
A lot of things changed and will require a full rewrite of our template...
I am getting other errors though when trying to dynamically load images into a table.
I'll upgrade to the trial version from the pro if we can ensure that this will be working properly.
I've started up another thread for current issues.
As it stands, phpdocx 4.0 does appear to have resolved image display issues for Mac users by switching to the WordFragments.
Thank you,
