Truly a nice template !  It's great to see GNUmed + LaTeX
being put to good use  :-)

I'd be scared. Please make sure its permissions are 0600 ...

I see the problem.

A trick can be employed:

        \includegraphics[whatever 
options]{/gnumed/signature-$<current_provider_external_id::MSP//CA 
BC::120>$.png}

You will then need to rename *your* signature file to

        /gnumed/signature-<whatever_your_MSP_is>.png

;-)

Eventually, a better solution is to enhance the staff table
to be able to hold a bytea field .signature able to store a
signature image. I would then recommend to store a GPG
encrypted version and have GNUmed ask the user and GPG to
decrypt it on demand.
