As you recall from Lesson 1 [What is HTML?], adding a paragraph in HTML is as simple as wrapping text in and
tags. Adding an image, however, is a little more complicated.Follow Along
Before we continue, I encourage you to follow along by copying and pasting today’s code into your own HTML document [or the page we created in Lesson 2: How To Create and Save Your First HTML File by Hand]. This will allow you to edit the text, and refresh the file in your web browser as we make edits. This will greatly enhance your learning ability.
A Funny Dog
Let’s pretend we have an image of a dog on our computer saved as “funny-dog.jpg” and we want to insert it into a webpage; this is the code we would use:
Let’s analyze this code. First, As you
can see, in both code examples so far there has not been an ending tag, because the image code is a “self closing” element. This is because unlike a paragraph, we won’t have a plethora of content inside our Self Closing Elements
That’s it!

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.

There are a few Base64 encoders online to help you with this, and this is probably the best I've seen:
//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];
}

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 it with files up to 2 MB size, JPEG and PNG.

I stumbled upon similar problem now and the solution is:
#!/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
