gEDA's PCB had this feature in the Xaw version; we haven't gotten
around to re-adding it in the latest version.

I used a similar method: taking a picture of the trace side, editing it,
flipping and possibly superimposing a photo of the component side. 
I then use a circuit drawing program such as Dia (it's native on Linux
but has been ported to Windows, too: http://www.gnome.org/projects/dia/)
to draw the schematics overlaid on the background image. 

Because the diagram program maintains the connectivity when elements
are moved around, I can rearrange and straighten up the topology of the
schematics, rats-nest like. If one could import background into a proper
PCB design program such as Eagle, one should be able to get back the PCB.

People do weird things. BTW, your "revised" posting has the incorrect
URL in it again! The link above works, of course...

Spam or merely a nonfunctional site? I get a generic parked domain sort
of page.

Hello all,

Although this is certainly elementary, I thought I'd share it since it 
may help someone in a pinch; here is my simple technique to create a 
preliminary schematic from a populated 1 or 2 sided pcb:
