title: Sudden 403 Error on Text Detection
body: <p>I was working with the standard example code for the text detection API and everything was working fine, but now if I try to run the same program (no edits made) on a new image, python returns the error:</p>
  
  <blockquote>
    <p>Http Error for /Users/lummish/Documents/Cloud Vision Tests/foodman.jpg 
    &lt; HttpError 403 when requesting <a href="https://vision.googleapis.com/v1/images:annotate?alt=json" rel="nofollow">https://vision.googleapis.com/v1/images:annotate?alt=json</a> returned "Request Issue Failed."></p>
  </blockquote>
  
  <p>Which in turn causes the following error:</p>
  
  <blockquote>
    <p>AttributeError: 'NoneType' object has no attribute 'items'</p>
  </blockquote>
  
  <p>I can't seem to figure out what's going on. I've tried getting a new keypair as well as cloning the project from scratch, but neither accomplished anything. Any help would be appreciated.</p>
