title: PyAutoGUI - No Such File or Directory Error
body: <p>Anyone have any luck on this ? I am tyring to recreate this <code>[tutorial code][1]</code> :</p>
  
  <pre><code>&gt;&gt;&gt; import pyautogui
  &gt;&gt;&gt; button7location = pyautogui.locateOnScreen('calc7key.png')
  &gt;&gt;&gt; button7location
  (1416, 562, 50, 41)
  &gt;&gt;&gt; button7x, button7y = pyautogui.center(button7location)
  &gt;&gt;&gt; button7x, button7y
  (1441, 582)
  &gt;&gt;&gt; pyautogui.click(button7x, button7y)
  </code></pre>
  
  <p>But I get the following error [at line 2 of the code above] FileNotFoundError: [Errno 2] No such file or directory: 'calc7key.PNG' when I have such file stored in  File "C:\Users*******\Desktop\Python\lib\site-packages\pyscreeze__init__.py", line 165, in _locateAll_python
      <strong>needleFileObj = open(needleImage, 'rb')
  FileNotFoundError: [Errno 2] No such file or directory: 'calc7key.PNG'</strong> ..anyone have any luck using this. essentially I am trying to screenshot a minimized tab to be opened by pyautogui (like lets say the google chrome icon at the bottom of my screen)</p>
