Image enlarges when I publish

When I publish a document with an image on the front cover, it is supposed to set it to front and center, but instead it takes up the entire page:

The image itself is not that large. Guides seems to be expanding it.

Here is the source: 

<?xml version="1.0" encoding="UTF-8"?>

    <image href="GUID-b4720b3e-04db-4a4a-8ac8-1d6a401fe5bd.png" id="image_1" outputclass="brand_logo">
    </image>
    <section id="section_1" outputclass="pds-frontpage">

      <ul id="ul_1">

          <p>Cleanable, self-draining design in vertical or horizontal orientation</p>
        </li>
      </ul>
    </section>
  </conbody>
</concept>

The outputclass=”brand_logo” is supposed to center the image on the page. I thought the issue might be that the image was a .jpg, but it didn’t work when I converted it to png. I also tried getting a new image from our Graphics team and got the same result. Image is attached. I’d appreciate any advice you can give me.
