title: Disable File drag & drop if there isn't a file input
body: <p>I think the solution to this is staring me in the face, but I can't seem to find it.</p>
  
  <p>So, I'm making a site that has a small file upload section. The upload section will have a place to upload an image for different devices and device orientations (i.e. iPhone, iPad, portrait and landscape). I can easily figure out how to implement the drag &amp; drop on the individual device icons, but if the user misses the drop area, the browser will just navigate to that image on their system. How do I disable drag &amp; drop if there isn't a file input type to receive the dragged file?</p>
