title: How to use CKEditor4 Upload Image using CDN?
body: <p>I'm trying to enable the <a href="https://ckeditor.com/cke4/addon/uploadimage" rel="nofollow noreferrer">Upload Image</a> drag and drop feature for CKEditor4. We have it hosted on our CDN at my job, and I've been adding plugins by simply adding them to the /plugins folder, and enabling them using <code>config.extraPlugins</code>.</p>
  
  <p>The documentation for the file manager (<a href="https://ckeditor.com/cke4/addon/imageuploader" rel="nofollow noreferrer">Image Uploader</a>) says to use <code>config.UploadUrl</code> to handle the image file upload. After adding the <code>uploadimage</code> folder to the CDN, I tried this, and nothing seems to happen. No errors in the console either.</p>
  
  <pre><code>CKEDITOR.config.extraPlugins = 'uploadimage';
  CKEDITOR.config.UploadUrl = 'https://cdn.cpscentral.com/js/ckeditor4-fuller/imageuploader/imgupload.php';
  </code></pre>
  
  <p>It also says <strong><em>Don't forget to set CHMOD writable permission (0777) to the imageuploader folder on your server.</em></strong> I'm not entirely sure how to do this, but I know that this s3 folder is public. Would really appreciate some guidance!</p>
