问题:

How can I embed a .png file into a blank "file.html" so that when you open that file in any browser you see that image? In this scenario the image file is not linked to from the HTML but rather the image data is embedded in the HTML itself.

回答1:

There are a few base64 encoders online to help you with this, this is probably the best I've seen:

http://www.greywyvern.com/code/php/binary2base64

As that page shows your main options for this are CSS:

div.image {
  width:100px;
  height:100px;
  background-image:url(data:image/png;base64,iVBORwA<MoreBase64SringHere>); 
}

Or the <img> tag itself, like this:

<img alt="My Image" src="data:image/png;base64,iVBORwA<MoreBase64SringHere>" />

The 64base method works for large images as well, I use that method to embed all the images into my website, and it works every time. I've done with files up to 2Mb size, jpg and png.

I don't know for how long this post has been here. But I stumbled upon similar problem now. Hence posting the solution so that it might help others.

#!/usr/bin/env perl
use strict;
use warnings;
use utf8;

use GD::Graph::pie;
use MIME::Base64;
my @data = (['A','O','S','I'],[3,16,12,47]);

my $mygraph = GD::Graph::pie->new(200, 200);
my $myimage = $mygraph->plot(\@data)->png;

print <<end_html;
<html><head><title>Current Stats</title></head>
<body>
<p align="center">
<img src="data:image/png;base64,
end_html

print encode_base64($myimage);

print <<end_html;
" style="width: 888px; height: 598px; border-width: 2px; border-style: solid;" /></p>
</body>
</html>

end_html

Quick google search says you can embed it like this:

<img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/
/ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcpp
V0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7" 
width="16" height="14" alt="embedded folder icon">

But you need a different implementation in Internet Explorer.
