madtoperl: it's a pity you didn't google this before you posted, otherwise you might have noticed this livejournal entry from "timwi" a few years ago that had the exact same problem (and nearly the exact same code, and wording, of your question).
It's reproduced here for your convenience:

Continued problems with binary files
Dear hackers again,
thanks for your hints in the previous entry. However, I'm still having
+ problems here.
How do I simply load a file into memory? Again, without corrupting any
+ line endings?
I've tried this:
#!C:\Perl\bin\perl.exe
use strict;
print "Content-Type: image/jpeg\n\n";
local $/ = undef;
open F, 'C:\Temp\temp.jpg';
binmode F;
my $content = <F>;
close F;
print $content;
and this produces a corrupt response. What is the correct way of loadi
+ng a binary file? Thanks for any help in advance.
