Hi

See URI::data - URI that contains immediate data

#!/usr/bin/perl --
use strict; use warnings;
use URI; use IO::File;
my $u = URI->new("data:");
$u->data(join '', IO::File->new( 'camel.favicon.png' , '<:raw' )->getl
+ines );
$u->media_type("image/png");
print qq[<p><img src="$u">\n];
__END__

FWIW, new questions go in Seekers Of Perl Wisdom

Welcome, see The Perl Monks Guide to the Monastery, see How do I post a question effectively?, Where should I post X?

data:-URLs are nice, but they have limits: Old browsers and especially IE<7 can't handle them, IE<9 has some arbitary limits for the data URL length. See http://en.wikipedia.org/wiki/Data_URI_scheme for a good overview.

Base64 encoding can be done from the command line, as documented in MIME::Base64.

Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)

I think I simply mailed it to myself and copied the base64 encoding.
