I look at it this way. If you have endured the treadmill and got
through to the stage where they are asking for photo's don't risk
messing it up by sending just one. You will no doubt have gathered
enough experience of the sysytem thus far to know that
you can do no harm by sending at least 5, better make that 10 just for
good measure.
Doesn't it just make you bitter eh?
Oh and get them signed by God and blessed by the pope just for
good measure
