    Try this simple test script

    #!/usr/bin/perl
use strict;
use CGI ':standard';
use CGI::Carp 'fatalsToBrowser';

my $file = "/cgi-bin/PTF//WP_20140410_19_01_49_Pro.jpg";

print header,
start_html('Test'),
img({-src=>$file,-alt=>'image'}),
end_html;

      The file system path will most likely not work - the -src path needs to be either relative to the web server root, or specially configured as a directory in the web server config.

      One possible option is to do: 

      my $file = "/cgi-bin/PTF//WP_20140410_19_01_49_Pro.jpg";

      which assumes that "/var/www" is the server root.

              What is the sound of Perl? Is it not the sound of a wall that people have stopped banging their heads against?

        The above error is from server logs .. /var/log/httpd/error_log.

        Do we have any other logs which can help to resolve this issue

    Current code is as below, but still the same error.

    Then look at the other stuff (not the code), the server configuration ... gather version info wherever you can

        Now I'm even more convinced this is a configuration issue ... whatever it is

        Good luck

    More information about this error may be available in the server error log.

    Have you checked the server error log?

[reply]
      I have been checking /var/log/httpd/error_log. Do we have some other log other than this ?

        Do we have some other log other than this ?

        Hmm, apache is usually called http and not tomcat, so are those apache or tomcat logs? maybe :)

    just for curiousity.. why you use non parsed header? 
    -nph => 1,
