Hello Again.
The original suggestion you supplied worked on the site the question was for. However I am trying it somewhere else and despite the HTML seeming to have an A HREF = added, the image does not behave as a link. Below is an example of some staging code, when I enter a URL it created the HTML >>>>
<li style="display: block; width: 100%; float: left; margin-right: -100%; position: relative; " class="slide-33 ms-image">
<a href="https://www.google.com/" target="_blank">
<img src="https://site.staging.com/wp-content/uploads/slider-1.png" class="slider3 slide-3" alt="image" rel="" title="blah slider image" srcset="https://etc" sizes="(max-width: 800px) 100vw, 800px" draggable="false" width="800" height="300">
</a>
<div class="caption-wrap">
<div class="caption">
<div class="Left-side">
<p>Small <a href="/shop/item-1/" class="Slider-1">Short bit of Image text </a> Available from Me!</p>
</div>
</div>
</div>
</li>
Any ideas as to why this will not work as a link, the text caption-wrap runs fine as a link, but not the main image?
