The "Comment Image" subform allows one to create or modify 
the comment on the image header of the image that is currently displayed; 
this feature is useful for documenting 
images.  A maximum of 512 characters can be used in the image header and the
file must be written out for the comment to be saved.  Enter the comment
in the comment parameter box.  When the comment is complete, click on the
"CHANGE COMMENT" button to initiate the change.
