I found the following in (I think) the comp.emulators.apple2 FAQ. Hope
it helps.  I haven't tried it.

                            EXTRACTING DISK-IMAGES

It is possible to convert a disk-image BACK to an Apple ][ 5.25"
disk. "UnImage v0.1" by Ivan Drucker <drucker@lclark.edu> will convert
disk-images back to disks. One of the options of "DSK2FILE 4.0" by Ron
Kneusel <rkneusel@post.its.mcw.edu> is to write an image file back to
5.25" floppy.  Alternatively, "DeImage v0.1" by Ivan Drucker extracts
Applesoft and Binary files from disk-images into ProDOS, although the
process will only work with standard DOS3.3 disks (ie. disks
possessing a catalog). Finally, "UnForkIt v0.1" also by Ivan Drucker
converts forked files on ProDOS volumes to one or two unforked
files. These utilities all require the disk-image to be on a mounted
ProDOS volume. "Apple Disk Transfer 1.20" by Paul Guertin
<guertinp@iro.umontreal.ca> can transfer a disk-image from MSDOS or
Macintosh to a 5.25" Apple drive via null-modem cable. Finally, it is
possible to create a "shrunk" disk-image in reverse. Having reordered
the disk-image into ProDOS Order (if necessary), use "Nulib" (version
3.2 or greater is required) to create a shrunk-disk (.sdk)
archive. Transfer the file back to the Apple and use ShrinkIt to
decompress the image back to a diskette.
