[Therion] Embedded image does not appear in some layouts

12 Feb 2025

      Here is a puzzle ...  I have set up a thconfig file to create a profiles 
map, then used the "map-image" layout directive to include it in the 
output files.  It works ...  SOMETIMES!

Take a look at the thconfig file embedded below.  The profiles image 
appears on the files produced from the MainMap and MainMapNoColor 
layouts.  It does not appear on MainMapPrint.

Why?  Does it have something to do with the TeX code in MainMapPrint?

Thanks!
