  <form id="form_upload_image_file_button" action="/testpage" method="POST" enctype="multipart/form-data">
      <input type="hidden" name="form_submit_id" value="testpage" />

      <label class="upload_image_file_button">Select a photo
        <input type="file" name="image_file" accept="image/*" multiple="false" onchange="form_upload_image_file_button.submit();" ">
      </label>
  </form>

  <form id="form_upload_image_camera_button" action="/testpage" method="POST" enctype="multipart/form-data">
      <!-- Note this button will only select the camera on mobile devices, on desktop it will open the file picker -->
      <input type="hidden" name="form_submit_id" value="testpage" />

      <label class="upload_image_camera_button">Take a picture
        <input type="file" name="image_file" accept="image/*" capture onchange="form_upload_image_camera_button.submit();" ">
