Can't figure out the appropriate selector

How to?
#1

I've created a scraper to extract a bunch of data from Mailchimp for my business (send date, open rate, clicks, subject line, etc). I've got everything working great but I can't figure out how to scrape the image url. I've copied and included both the selector and element from Chrome's inspect feature for the container with the image. Can anyone tell me what the appropriate selector would be from it?

Selector
#templateHeader > tbody > tr > td > table > tbody > tr > td > table > tbody > tr > td > a > img

Element

<td class="mcnImageContent" valign="top" style="padding-right: 9px;padding-left: 9px;padding-top: 0;padding-bottom: 0;mso-table-lspace: 0pt;mso-table-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;" 
     <a href="https://www.getdeclan.com/collections/all?&amp;utm_medium=newsletter&amp;utm_campaign=30mre" title="" class="" target="_blank" style="word-wrap: break-word;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%;">
                                    <img align="left" alt="" src="https://mcusercontent.com/85b93e43230b2aa4c86a77e6b/images/dfd47132-91e5-4fe4-96e4-081ae50d8089.jpg" width="564" style="max-width: 740px;padding-bottom: 0;display: inline !important;vertical-align: bottom;border: 0;outline: none;text-decoration: none;-ms-interpolation-mode: bicubic;" class="mcnImage">
                                </a>
                            
                        </td>

Try:

Type: Element attribute
Selector: td > a[target] > img
Attribute name: src
