title: How file upload send the image file (in which form)?
body: <p>When I load the file using type = "file" <br/>
  it selected any extension from the folder. <br/>
  then my question is 'how this file formed to send it to other  server or page?'</p>
  
  <pre><code> &lt;form action="/action_page.php"&gt;
        &lt;input type="file" name="pic" accept="image/*"&gt;
        &lt;input type="submit"&gt;
      &lt;/form&gt;
  </code></pre>
  
  <p>let say I selected the file    image.jpg. 
  how this image.jpg transformed? 
  and where they stored? 
  <br/>
  and how they send this file?<br/></p>
  
  <p>I'm asking this question because <br/>
  Im using webview on android <br/>
  when I access to the android gallery file it retuned some bitmap format.<br/>
  I want to know how to send this bitmap format on </p>
  
  <pre><code> &lt;input type="file" name="pic" accept="image/*"&gt;
  </code></pre>
