create mountable image of installation dvds

["Russell L. Harris" <rlharris@broadcaster.org>]

I purchased a Bible concordance program for the i386, and received the
program on a set of DVDs.  The problem is that I need to install the
program on a laptop which has no optical drive, but only USB ports.  

So it appears to me that I need to find:

    (1) a procedure for creating a set of DVD images (using a desktop
    machine with a DVD optical drive), and 

    (2) a procedure for copying the images to a set of USB flash
    sticks, so that the images can be read as if they were on DVD.
