I am looking for the easiest way to help her view this on her iPad - it would be easier for me if she wasn't 2000 miles away -

dmg files are disk images, which the ipad does not support. she needs to double-click the dm and then copy the book/magazine from the dmg to the mac.
then the question is what format is that file and can the ipad read it.
if it's a common format like pdf or epub, it will just work. sync it with itunes.
if it's something else, then it may need to be converted, and if it requires a custom app to view it (which is my guess since why else would it be distributed on a dmg), then it may not work at all unless there's a native ipad app.
