Re: 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;` [download] And then you don't even have to type `binmode STDOUT` as another monk in this thread suggested, because `copy` does it for you. -- Randal L.

don't forget `binmode STDOUT;` [download] before you print the image to standard out... Jouke Visser, Perl 'Adept'	[reply] [d/l]
