How do I insert in a cell a link to display a JPG file in window
 

I am using Excel to build a catalog of 100 items that can be sorted. In one
of the columns, I want to use a humbnail of the JPG file associated with the
item in the row. I want to click on the thumbnail to display the JPG file in
a window.
How do I place the thumbnail in the cell, link to the JPG file, and cause
the file to be displayed?
Thanks,
LJL
