what you want should work as you did it, so it must be some other error,
e. g., this works:

\pdfximage width 100mm{PM661.JPG}
\edef\firstimage{\the\pdflastximage}
\hbox{\pdfrefximage\firstimage}
\vfill\eject abc
\vfill\eject abc
\vfill\eject abc
\vfill\eject abc
\hbox{\pdfrefximage\firstimage}
\bye
