title: ImageMagick no decode delegate
body: <p>I'm trying to convert an image with imagemagick, but I'm getting this error:</p>
  
  <blockquote>
    <p>convert: no decode delegate for this image format `//i.imgur.com/nTheJ.jpg' @ error/constitute.c/ReadImage/532.</p>
  </blockquote>
  
  <p>I'm doing this:</p>
  
  <pre><code>convert http://i.imgur.com/nTheJ.jpg -resize 600×600 filarkiv/billeder/produkter/s236-085145.jpg
  </code></pre>
  
  <p>I have the following delegates:</p>
  
  <blockquote>
    <p>DELEGATES     freetype jpeg jng mpeg png x11 xml zlib</p>
  </blockquote>
  
  <p>Anyone knows what the problem is?</p>
