title: Google photos api - Access-Control-Allow-Origin
body: <p>I am building a design tool to create fully customizable photo products like photobooks. I use technologies such as firebase (database and storage) and angular4. In order to integrate google photos with my web app I use the google photos api. When I try to edit user's photos with html canvas (toDataUrl) I get the following error: <br>
  <strong>"Access to Image at '...' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."</strong> <br>
  I know what it means but i can't find any solution in order to edit user's photos and use them for printing purposes. Could anybody help me?</p>
