<p>Why isn&#8217;t this an <tt class="docutils literal"><span class="pre">ImageField</span></tt>?</p>
<p>For <tt class="docutils literal"><span class="pre">ImageField</span></tt>s, Django checks the file system for the existance of the files to handle the height and width. In many cases this can lead to problems and impact performance.</p>
<p class="last">For these reasons, a <tt class="docutils literal"><span class="pre">FileField</span></tt> that manually manages the width and height was chosen.</p>

<div class="admonition note">

<p>Why isn&#8217;t this a <tt class="docutils literal"><span class="pre">URLField</span></tt>?</p>
<p class="last">For <tt class="docutils literal"><span class="pre">URLField</span></tt>s, Django checks that the URL includes <tt class="docutils literal"><span class="pre">http://</span></tt> and the site name. This makes it impossible to use relative URLs in that field.</p>
