title: Rails 4 image-path, image-url and asset-url no longer work in SCSS files
body: <p>Are we supposed to use something else aside from <code>image-url</code> and others in Rails 4? They return different values that don't seem to make sense. If I have <code>logo.png</code> in <code>/app/assets/images/logo.png</code> and I do the following, this is what I get:</p>
  
  <pre><code>image-url("logo.png") -&gt; url("/images/logo.png") #obviously doesn't work
  image-path("logo.png") -&gt; "/images/logo.png"
  asset-url("logo.png") -&gt; url("/logo.png")
  </code></pre>
  
  <p>Of course none of these work because they need at least <code>/assets</code> in front.</p>
  
  <p><em><strong>UPDATE</em></strong>: Actually, I just noticed, how do I access images in Rails 4? I have an image at <code>/app/assets/images/logo.png</code>. But if I go to any of the following URLs, I still don't see my image:</p>
  
  <pre><code>http://localhost:3000/assets/logo.png
  http://localhost:3000/assets/images/logo.png
  http://localhost:3000/logo.png
  http://localhost:3000/images/logo.png
  </code></pre>
  
  <p><em><strong>UPDATE 2</em></strong>: The only way I can bring up my <code>logo.png</code> is by moving it into the <code>/app/assets/stylesheets</code> directory and then pulling up:</p>
  
  <pre><code>http://localhost:3000/assets/logo.png
  </code></pre>
