title: How to find cells that contain images with openpyxl
body: <p>I am looping through every cell in a workbook. For some reason, when openpyxl iterates through a worksheet that contains an image, the image is deleted. How does one fix this?</p>
  
  <p>I am looking for a way to pass over cells that have an image.</p>
  
  <p>I am not in <code>read_only</code> mode, and do not desire to be, as I am making modifications to the worksheets.</p>
  
  <p>Something like this would be most useful to me:</p>
  
  <pre><code>if cell is image:
      pass
  </code></pre>
