                                 IMAGER Rev 1.0         Oct. 1994


        Current Software status:  FREEWARE
        ------------------------


        Functional Restrictions:
        ------------------------

        o  Only 3 images can be processed at once; (meaning that only
           3 image files can be active and simultaneously visible on 
           the screen; to view an additional image, 1 of these must
           be deleted)

        o  This FREEWARE version is single-threaded; when an image file
           is being retrieved from disk, other activity stops.


        Caveats:
        --------

        o  The optimal video setup for this version of IMAGER is:

                256 Colors
                1280x1024  or  1024x768  resolution

           It has been tested at lower resolutions, but since the
           images are 800x800, there is some loss.

           It has not been test at 16 colors; 65536 colors will
           display an image but the default color map produces a
           dingy green/brown image.

           These issues will be worked.

        Installation Procedure:
        -----------------------

        o  This Installation procedure DOES NOT modify your DESKTOP
           or existing *.ini files in any way.  Running the program
           will create an IMAGER.INI file on the 'C' drive.

        o  This product only runs under OS/2 ver 2.1 or higher.
           It has been tested with WARP v3 version of OS/2.

        o  Make sure you have the required disk space for program
           files. Current rev needs 3.5 meg.

        o  Create a subdirectory to contain files. This can
           be on any drive.

        o  Copy all the files on the diskettes to the new subdirectory.

        o  The files are 'Zipped' for compression; if you don't have
           a version of UNZIP.EXE or PKUNZIP.EXE that works, one may
           be obtained from the same BBS where you downloaded this file.

           Go to the directory where you have copied the IMAGER
           files and issue the commands:

                UNZIP (or PKUNZIP)  IMAGER1.ZIP

           When that finishes, enter:

                UNZIP (or PKUNZIP)  IMAGER2.ZIP

        o  You are now ready to run the IMAGER software.  Just
           enter:
