in reply to How can I use a CGI script to return an image?

Supposing your image is in a file, and you want your script to stream its contents on-demand: 
open IMAGE, "/path/to/image.jpg";
#assume is a jpeg...
my ($image, $buff);
while(read IMAGE, $buff, 1024) {
    $image .= $buff;
}
close IMAGE;
print "Content-type: image/jpeg\n\n";
print $image;

or, faster and easier: 
use File::Copy;
print "Content-type: image/jpeg\n\n";
copy "/path/to/image.jpeg", \*STDOUT;

    Or simpler (because I hate typing): 
    use File::Copy;
print "Content-type: image/jpeg\n\n";
copy "/path/to/image.jpeg", \*STDOUT;

    And then you don't even have to type binmode STDOUT as another monk in this thread suggested, because copy does it for you.

    don't forget 
    binmode STDOUT;

    before you print the image to standard out... Jouke Visser, Perl 'Adept'
