If I remove the _setup stuff, slidedeck runs fine but does not find any
images to load. Putting _setup back and running with
@app.before_first_request commented out does not appear to change
anything. Neither of these throws an error in the apache log.

I need to go pick up my kids but I will try again tomorrow.

deepzoom is working fine so we must be close - thanks very much!
