Hello. I've got a program that displays a thumbnail picture of a house's
floorplan within a Userform, based on the house selected by the user. What
I'd like to do is allow the user to double click on the image and have it
open up in the user's default image viewer, so they might view, edit or
print the floor plan out.

After 2 hours of searching, all I've come up with is the fact that I might
be able to do it with the Shell command but I don't know if that will work
unless I declare the location of the picture viewers exe... which can
obviously changed based on the user's PC.

Any guidance would be very appreciated.

Thank you very much for your time!
