title: Github readme image embeds in private repo?
body: <p>I'm trying to embed an image in my <code>readme.md</code> for display on GitHub. I've had no trouble doing this before with public repositories, in this format:</p>
  
  <pre><code>![header image](https://raw.github.com/account/reponame/master/myimage.png)
  </code></pre>
  
  <p>I'm now doing the same for a private repo that lives under an organization account and getting a 404. If I navigate to the image in the repo and get the raw URL, I get something like:</p>
  
  <pre><code>https://raw.github.com/account/reponame/master/myimage.png?login=jackaperkins&amp;token=b295d913f6bf6e5cf1115755fb05e770
  </code></pre>
  
  <p>Is there a way to tell GitHub to embed the real authenticated URL? I figured the access to the resource would be controlled with sessions outside of the URL but apparently not.</p>
