Thanks Jeremy. I think this 'pdftoppm' will do what I need.

The reason I need a jpg is to get photos printed (from Costco)
for four reasons: #1 to make sure all the colors are correct,
#2 to be able to make individual photo prints in various sizes
for various marketing needs, #3 to send a photo print color proof
to our book printer in Michigan for color verification/matching,
and #4 because I do not have a high-res color printer and I am not
aware of any place locally where I can get a pdf files printed in
high-res color and various sizes. I called Kinko's and didn't get
a satisfactory response (or price) from them.

Thanks again to you and to all who offered suggestions.
