 Adds, multiplies, divides or subtracts two images.

 Command parameters -

 IMAGE  The name of the structure containing the first image.

 IMAGE1 The name of the structure containing the second
        image data.

 OUTPUT The name of the result of the operation.  This can
        be the same as for IMAGE.  If not, a new structure
        is created, with everything but the data (and any error
        or data quality information) a direct copy of the first
        image.

 The command itself (IADD,IMULT,IDIV or ISUB) is used to
 differentiate between the two operations.
