Using Perl to Display Picture

Posted on 2006-11-29

my directory structure is /home/p/public_html/cgi-bin/
I am trying to display a pic (using perl)outside of public_html ... I tried doing      

header ('image/gif');
print "<IMG SRC=\"/home/p/pic.gif\">";

but when i render it i realise it is looking for the picture  at www.servername.com/home/p/pic.gif 
and i guess since it doesn't have permission for /home/p it just diplays the red x.  

How can i solve this problem?

Thanks

Yes, public_html is normally set up for everyone to read. You could grant read access to all on the diretory /home/p
Your HTML may also be set up to define a base reference point of /home/p/public_html

You need to do

#!/usr/bin/perl
use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser);

my $q = new CGI;
print $q->header('image/gif');
open IMG, "/home/p/pic.gif" or die "Can not open pic.gif $!\n";
binmode IMG
print <IMG>;
close IMG;

I tried using the suggestion by Tintin and I get a bunch of garbled text printed to screen ... what do i need to do to convert it to an actual image.

What browser are you using?  Have you opened the image directly in the browser previously?

I am using internet explorer.  I can open the image perfectly directly when its in public_html.  I know its reading the image file, can you give me an idea why i would see garbled data rather than pic. is there some header i may not be including?

The code you sent works perfectly, thank you... I guess it has something to do with the fact that I am also printing text  data in the same perl script.  I just tried using your code without any other code and it works.  

Thanks for your help

You can't mix content types (as you found out).
