OK - that's enough to get me going, thanks.  I'll look over the weekend. 
I'd not picked up the terminology of dev/web-build being a branch off 
lily-git.

Hmm.  If you set up the computer following the CG for a standard set up, 
what I say is true.  I've just nuked lilypond-git on my new PC and started 
from scratch, so this is a true test.  I configure build and run make 
website from scratch, with no previous make.  The output from this includes:

cp Documentation/pictures/out-www/* out-website/website/pictures ;

which would be fine, but Doc/pic/out-www is empty at this point, so no 
pictures are copied across and so no pictures appear on the website thus 
generated.  If I look at the introduction, for example, flat design isn't 
there.  That particular image is created from this line during make doc:

ln -f /home/phil/lilypond-git/Documentation/pictures/flat-design.png 
out-www/flat-design.png

The examples are the same.  After make website, they're not there.  Looking 
at make doc, we have (for the first example)

Processing 
`/home/phil/lilypond-git/Documentation/web/ly-examples/bach-bwv610.ly'
mv ./out-www/bach-bwv610.preview.png out-www/bach-bwv610.png
pngtopnm out-www/bach-bwv610.png | pnmscale -w=600 | pnmtopng > 
out-www/bach-bwv610-small.png

(these aren't together in the make output, I've extracted them).

So - in a normal user environment, make website _does not_ create most of 
the pictures.  And it doesn't copy them from another previously created 
cache.  It relies on make doc to create them, and then copies them from 
there.

Clearly, using the instructions to create a standalone website that we put 
into the CG, this isn't true.  But it is true for make website on a standard 
system.
