title: PIL UnidentifiedImageError with TIFF
body: <p>I have documents where each page is an individual tiff file. So i am using a python script to combine pages of the same document into a single multiframe tiff file. When i come to read some of my tiff files into memory using</p>
  <pre><code>opened_images_list.append(Image.open(directory_path + '\\' + f, formats = ['tiff']))
  </code></pre>
  <p>Then i get the error <strong>PIL.UnidentifiedImageError: cannot identify image file '\\windata1\data\IntelligentCapture\2015\01\26\42030593568-1'</strong></p>
  <p>If I open the image in paint and then save it as a TIFF i can then read it into PIL but this happens to be thousands of images.</p>
  <p>I used tifffile to have a look at the image using</p>
  <pre><code>python -m tifffile '\\windata1\data\IntelligentCapture\2015\01\26\42030593568-1' 
  </code></pre>
  <p>and this was the output:</p>

  <p>What can i do to get PIL to read this image?</p>
