title: Generate single thumbnail for Photoshop *.psd files
body: <p>I want to generate one single JPEG image file for PSD formats using any software. </p>
  
  <p>I tried ImageMagick but it's converting every layer into different images. </p>
  
  <p>I also tried exiftool. It got converted to one single image but quality is very bad. </p>
  
  <p>This is my code in ImageMagick:</p>
  
  <pre><code>convert filename.psd -thumbnail 340x340 testing.jpg
  </code></pre>
  
  <p>This is exiftool : </p>
  
  <pre><code>exiftool -Photoshop:PhotoshopThumbnail -b -resize filename.psd &gt;z1.jpg
  </code></pre>
