title: Pillow cannot read different TIFF files
body: <p>I'm using Pillow 2.2.1 (installed it with pip) on Ubuntu Server 12.04 64-bit and trying to batch resize images into jpeg format. I've also installed both zlib1g-dev and libtiff-dev with apt-get.</p>
  
  <p>I use the following line</p>
  
  <blockquote>
  <pre><code>   Image.open(path/to/image)
  </code></pre>
  </blockquote>
  
  <p>to open the image files (jpeg and tiff's). I can open some tiff images, but for others I just get the following error:</p>
  
  <blockquote>
  <pre><code>   File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 2006, in open
       raise IOError("cannot identify image file")
  </code></pre>
  </blockquote>
  
  <p>Since this doesn't occur for every tiff image I try to open does this mean that these files are corrupted? I have no problem opening the images in question with windows photo viewer or even with GIMP though.</p>
  
  <p><strong>Note:</strong> All the images were just given to me by my client so I have no idea how he digitized the images (scanned or took a picture of them is my best guess), or if that even matters.</p>
  
  <p>Am I missing a package or dependency, or is there really just something about the image files that I'm not seeing?</p>
