  NO.  Once you save the file as .jpg, some detail will be lost.  YOU
CANNOT GET IT BACK.

  If you expect to want to do more changes to the graphic, keep a copy
of the .BMP file.  Make your changes to it, and save a *new* .JPG file.

  Think of "saving to .jpg" as like "cutting a record".  To re-mix the
