This routine creates a database storing images taken of cores
and links them to depths in the holes for reporting and viewing.
The command will read both JPG and BMP files. When initially
running the command, a propmt will appear to select the file, which
creates a DHI file.
Then, in the assignment dialog the
drillholes are listed on the left side. The highlighted hole shows
up as a column on the right. The intervals for each photo are added
to the middle section. Selecting the green + button adds a line in
the window. The From and To Elev must be set for each image
interval. As each is entered, the core image shows up on the right
in the column for each interval. The Diameter controls how wide the
column appears on the right. 
Reports are generated of all the holes on the list with the
Report button. An example appears here.
