Sorry John Ralls, if my reply comes directly to you, my email client no 
longer lets me easily reply directly to the list only.

I have not been able to convert my data to an sql file, period. 30 years 
worth.  Works for other sets of books with much fewer years of data.

What I am after is a way to link images to a transaction but not via a 
specific filename.  Like many others I am sure, I'd like to access the 
images from any drive, including a replacement drive. I just had 2 hard 
drive failures back to back on external drives. Now not only do I have 
to hire a forensic company to try and recover them, I have lost all 
images saved to them.  And yes, they were both unfortunately system back 
up drives. 12 terabytes for those 2.

In fewer words, I need a method of attaching images to a stand alone 
database.  I have never had a successful build of GNC.  Some stupid 
mistake on my part I am sure.  I would be more than happy to write such 
program but I do not understand the GNC code well enough to change the 
image link from a file to a call to a standalone database program 
running in the back ground.
