Pictures do not load in email template
I have got two mailings. I created a workflow which requests JSON product recommendations to Target. Then I put urls/product name, price etc. into html.
- One has an h2 with a header. It looks like this the pictures are not loaded.

- The other doesn't have it the div with text and it works ... Pictures are loaded

HTML is like this. If I add bold element then the product pictures does not work:
<div style="text-align: center; padding-bottom: 20px;">
<img src="https://demo-system-next.s3.amazonaws.com/assets/luma/banners/AdobeStock_570499457.jpg" alt="Banner Image" style="width: 100%; border-radius: 8px;">
</div>
<div>

<img src=<%= variables.x7 %> alt="Column 3" style="max-width: 100%; height: auto;"> </img>
<p><%= variables.x8 %></p>
</div>

</div>
Do you you have any ideas why is that? How to debug this?
