title: AutoCAD Plugin Can't Locate Resources
body: <p>I have written an AutoCAD plugin that displays images based on what form item the user has selected. An example of an image being called to display would be</p>
  
  <pre><code>previewBox.Image = System.Drawing.Image.FromFile("Window Width.PNG");
  </code></pre>
  
  <p>However, even though the .PNG file is in the same directory as my .DLL file, I get an error saying the image cannot be located. The full error text I get is below.</p>
  
  <pre><code>Application does not support just-in-time (JIT) debugging. See the end of this message for details.
