title: Plotting list of picturelists in several plots
body: <p>I'v got a list with picture-path's and i want to "plot" them in several plots e.g:</p>
  
  <pre><code>list = [['./path1/pic1.jpg','./path1/pic2.jpg',...],['./path2/pic1.jpg',...],[...]]
  </code></pre>
  
  <p>the output has to be in this e.g 3 plots with the pictures from the list's</p>
  
  <p>i've tried that way but it seems to be not right because i get this Error </p>
  
  <pre><code>    fig, ax = plt.subplots(len(list))
      for image in list:
          im = Image.open(image)
          ax.imshow(im)
  
  
  AttributeError: 'numpy.ndarray' object has no attribute 'imshow'
  </code></pre>
  
  <p>I also tried <code>im = mpimg.imread(image)</code> which gaves me the same result and <code>ax.imshow(image)</code> without any "opening"</p>
  
  <p>maybe someone know how do do this...</p>
