title: Retrieve Publishing image field with Sharepoint 2013 REST Api / CSOM
body: <p>We're using the Sharepoint 2013 REST API to get all news items from the Sharepoint.
  We made a custom ContentType 'Newsitem' with several properties including a Publishing Image Field.</p>
  
  <pre><code>  var contentTypeId = "0x01100018B03AC7E8312648AEA00851DEDBCAF802";
    var standardUri = "https://examplesite.com/blog/_api/lists/getbytitle('Messages')/items?$top=7&amp;$filter=startswith(ContentTypeId,'" + contentTypeId + "')";
    var selectiveUri = "https://examplesite.com/blog/_api/lists/getbytitle('Messages')/items?$top=7&amp;$filter=startswith(ContentTypeId,'" + contentTypeId + "')&amp;$Select=Title,Teaser,Body,ShowAt,TeaserImg";
  </code></pre>
  
  <p>Using standardUri for my REST call, I retrieve all properties but no TeaserImg.
  Explicitly selecting TeaserImg makes the call fail of course.</p>
  
  <p>Why can't I find the TeaserImg, isn't this possible with Sharepoint 2013 REST Api and should I use CSOM instead?</p>
