Gnash is the wriong tool for this, but there is swfextract in the
swftools package
that will do exactly what you want. apt-get install swftools && man swfextract

You'll need to know the object IDs of the jpeg images. For example, to
barf the first 10 objects you can use

for a in 1 2 3 4 5 6 7 8 9 10
do
    swfextract --jpegs $a --output image-$a.jpg inputfile.swf
done

This will complain about non-jpeg objects but hey.
Similarly there is a --pngs flag if they images are stored as PNGs in
the SWF file.

For an automated error-free dump I guess you'd want to generate the
right JPEG and PNG object numbers from the output of some tools like
swfdump or swf_dump

Run
    ./autogen.sh
rather than running autoconf manually.

There is a specific guide to building on Debian in the Gnash wiki.
