Hmm... I tried a similar route before coming to the monastery: 
open my $fh, "<", $image_file
    or die "Can't open $image_file: $!";
my $raw = <$fh>;

Which I believe is the same as the slurp() function mentioned above. It failed. I tried your code too, with the same failure. The file has to be under 700K and my test files have definitely been below that. There must be something else going on. Unfortunately the error messages returned don't provide much help.

Thanks for your help!
