<tr>
        <td align="center" valign="middle" >
            <img src="htttps://onlinejpgtools/images/examples-onlinejpgtools/orange-flower.jpg"
                alt="Image" width="200px" height="200px">
        </td>
    </tr>

In this code the image is being applied and will show broken image icon in email because I have intensionally added htttps instead of https to show broken image icon so that scenario can be recreated.
