in reply to Display text and image on same page

It looks like the image is a graph that changes all the time, so using an inline base64 encoded image might make sense here. Something like: 
#!/usr/bin/perl
use strict;
use warnings;
use MIME::Base64 qw(encode_base64url);

my $img="/var/www/grafika/graphHour.png";
open(IMG,$img) or die "Can't open $img: $!\n";
my $imgdata;
{local $/=undef;$imgdata=<IMG>;}
close IMG;
my $b64=encode_base64url($imgdata);

print "Content-type: text/html\n\n ";
print "<html> \n";
print "<head></head>\n";
print "<body>\n";
print "<img src='data:image/png;base64,$b64'>";
print "</body></html>"

    inline base64 encoded image

    Bad news: Still not supported by all browsers (details). As usual, Microsoft's browser implementations cause trouble.

      It works fine on IE and Edge, since IE9, for this specific use case of the src element of an img tag. The only restriction is that it must be less than 4GB. That's described on the page you linked. There are other limitations for different use cases, but not this one.
