I realise you're very unlikely to find an existing /tmp/md5$$.txt
for the current process id but, just in case, I'd feel more comfortable
deleting it first otherwise one could wind up thinking all the
images are duplicates and deleting the lot, or something.

Ditto, don't see the point of append rather than straight redirection
to ${PICFILE}.
