I suspect that you're running into issues in GD.pm and dieing in the module. Before the above line put the following line to make sure the script sees your image file. 
unless(-e "churchmiddle.jpg"){
  print "can't see the image";
}

Unless churchmiddle.jpg is sitting in the directory with the script GD will die complaining about undefined values.
