### Get graphic:
my $graphic = shift @ARGV || die "usage error: missing path to graphic\n";
(-r $graphic) or die "$graphic unreadable\n";
my $graphic_type;
if    ($graphic =~ /\.gif$/i)   { $graphic_type = "image/gif" }
elsif ($graphic =~ /\.jpe?g$/i) { $graphic_type = "image/jpeg" }
elsif ($graphic =~ /\.png$/i)   { $graphic_type = "image/png" }
else                            { die "unknown type for: $graphic\n"; }
my $gid = "my-graphic";

### Get destination:
my $dest = shift @ARGV || die "missing destination\n";

### The top-level message:
my $msg = MIME::Lite->new(To      => $dest,
                          Subject => 'A postcard for you',
                          Type    => 'multipart/alternative');


### Alternative #1 is the plain text:
my $plain = $msg->attach(Type => 'text/plain',
			 Data => ["Having a wonderful time... \n",
				  "wish you were looking at HTML \n",
				  "instead of this boring text!\n"]);

### Alternative #2 is the HTML-with-content: 
my $fancy = $msg->attach(Type => 'multipart/related');
$fancy->attach(Type => 'text/html',
	       Data => [qq< <H1>Hey there!</H1> \n>,
			qq< Having a <I>wonderful</I> time... take a look!\n >,
			qq< <BR><IMG SRC="cid:$gid" ALT="Snapshot"> <HR> >]);
$fancy->attach(Type => $graphic_type,
	       Path => $graphic,
	       Id   => $gid);


if ($dest eq '-') {
    $msg->print;
}
else {
    $msg->send;
}
