Master page image doesn't display on content page
<p>I have an image on my master page like this:</p>

<pre><code>&lt;img src="../Images/logo.jpg" /&gt;
</code></pre>

<p>The master page lies in <code>Root/MasterPages/masterpage.master</code></p>

<p>Now this image is displayed in a content page which is in <code>Root/SomeDir/ContentPage.aspx</code>,
but it doesn't work in a content page which is in <code>Root/SomeDir1/SomeDir2/ContentPage.aspx</code>. Why?</p>
