Gaius and Ralph,
I like this one more too.  The reason for asking was more or less getting a 
hint of argument handling of the macros. I took a while to see that one of 
'-R' or '-L' is mandatory, not optional like the comment:  
.MPIMG [-R|-L]  ....
suggests when using the [...] syntax.
Look for example at line 531 or 583, the picture is always $2, the second 
macro argument. That means, deciding that
-R | -L      is  $1
-G gap       is  $2 and $3
image        is  $4
 - and really optional
width        is  $5
height       is  $6

implementing '-G gap' is than simple and straight forward
Do you all agree ?

Regards
 Heinz
