Thanks. I loaded the JPEGS into DPlngScan and saved them with the
quality set at 100% so as to lose no definition. They doubled in
byte size but saving them as Sprites increased some by a factor of 10,
so I was better off.
They then all loaded, as JPEGS, straight in into OPro and by reference.
They were in fact page pictures from a book and I wished to make a PDF
file of them. Loading all the pictures by reference gave an OPro file
of only a few k. Curiously, using PDF Print to make the PDF file it
ended up at 25% of the size of the sum of the JPEGs, very efficient;
there is a very minor degradation in quality at 200% scale.
