How do I extract .dsk image files???

[ToasterKing <toastjuice@aol.com>]

Call me stupid, but I can't figure out how to extract some .dsk image
files I got off the net somewhere.
When I got them they were gzipped, and after I FINALLY got them ungzipped
using that stupid little MacGZip program, I couldn't figure out what to
do with them.
They are .dsk files, which are dust sector-by-sector dumps of 5.25"
floppies.  Sounds simple, doesn't it?  I thought I could do it the modern
way using ShrinkIt GS, but it won't recognize them.  I fiddled around
with them a little in ProDOS BASIC, but still can't figure out how the
disks were put into that form.

If anybody can help me out, please drop me some mail at toastjuice@aol.com

Thanks!
