Hi Jonathan,
Try this:
Toward the top left of the browse files dialog, there should be a little
double-icon thing with four horizontal stacked lines on one side, and a
three-column table on the other. Activate the three-column table, instead
of the stacked lines, and you should be able to get thumbnails instead of
just name and date modified. OS setting, not Word.
If that isn't it:
Sounds like an OS issue. Those type of dialogs are mostly created by the OS,
with maybe a little input from Word. What version OS do you have?
I do see thumbnails in Insert | Picture | From File, so it may have
something to do with your pictures. Do you see thumbnail previews in a
regular Finder window?
Side note:
If these photos are kept in iPhoto, see Michel Bintener's post on this
thread for an Automator tip for easy access to those:
