Using createElement('img') to get .jpeg instead of .png
<p>I would like to use createElement("img') to create .jpeg extension instead of .png </p>

<blockquote>
  <p>For jpeg image type, the second argument should be a number between 0
  and 1 specifying the image quality level.</p>
</blockquote>

<p>I am not sure what the syntax for the code would be.</p>

<p>Is it something like this?</p>

<pre><code>createElement("img",1)
</code></pre>
