Re: Returning jpg works, png NOT

Note that this serves no purpose:

binmode IMAGE;
...

open IMAGE, $file_name or die "ERROR $!";
[download]

You need to appüly binmode after opening a file (but before reading from it):

open IMAGE, $file_name or die "ERROR $!";
binmode IMAGE;
[download]

Good catch! That, in fact, could explain the symptoms, because the magic bytes of the PNG format (`"\x89PNG\r\n\cz\n"`) is specifically designed such that it becomes corrupted if you mess up line endings, whereas a small jpg image might not contain `"\r\n"` anywhere at all so it may survive being read in text mode.

Thank you, Corion! This solved it, and "good catch" indeed...	[reply]
