Broken images!

Hello, I am working on this custom html question, the images display fine in my preview but like broken images on the survey preview (adding in a screenshot). Does anyone know why this may be the case? I am also pasting my code below. 

  <!-- Main Container with Background Image -->
  <div style="position: relative; width: 600px; height: 600px; background-image: url('https://uwartsandsciences.pdx1.qualtrics.com/ControlPanel/Graphic.php?IM=IM_VHOdoYnAyqTK5Lt'); background-size: contain; background-position: center; background-repeat: no-repeat; border: 1px solid #ccc;">
    <!-- Grid Cells -->
    <div class="grid-cell" data-location="R1C1" style="position: absolute; top: 40px; left: 20px; width: 190px; height: 190px; border: 1px solid rgba(0, 0, 0, 0.1); display: flex; justify-content: center; align-items: center; box-sizing: border-box;"> </div>
    <div class="grid-cell" data-location="R1C2" style="position: absolute; top: 40px; left: 200px; width: 190px; height: 190px; border: 1px solid rgba(0, 0, 0, 0.1); display: flex; justify-content: center; align-items: center; box-sizing: border-box;">&nbsp;</div>
