The difficulty in viewing Mimi's cemetery plan is due to the file name not
being one of the standard types for a picture file.
The name of the file as sent by Mimi was "cz.cemet". This is not a standard
name for a picture file, which should have a standard ending such as ".jpg",
I easily solved this problem by renaming the file.
I suggest you rename the file as something like "cemetery-plan.jpg" (the
".jpg" is the important bit). Then you will find that you can view the file
fine - no problems!
Hope this is helpful.
