Django ImageField core=False in newforms admin
<p>In the transition to newforms admin I'm having difficulty figuring out how specify core=False for ImageFields.</p>

<p>I get the following error:</p>

<pre><code>TypeError: __init__() got an unexpected keyword argument 'core'
</code></pre>

<p>[Edit] However, by just removing the core argument I get a "This field is required." error in the admin interface on attempted submission. How does one accomplish what core=False is meant to do using newforms admin?</p>

<p>The <code>core</code> attribute isn't used anymore.</p>

<p>From <a href="http://oebfare.com/blog/2008/jul/20/newforms-admin-migration-and-screencast/" rel="nofollow">Brian Rosner's Blog</a>:</p>

<blockquote>
  <p>You can safely just remove any and all <code>core</code> arguments. They are no longer used. <em>newforms-admin</em> now provides a nice delete checkbox for exisiting instances in inlines.</p>
