Others may have better solutions, but I think the position jumping on click can be cured by putting each of the anchor elements in <div> tags, and transferring the <a> tag classes to the <div> tags as follows.

<div class="nmark">
<a href="https://www.napit.org.uk/" target="_blank"><img src="images/napit.jpg" alt=""></a>
</div>
<div class="tmark">
<a href="https://www.trustmark.org.uk/" target="_blank"><img src="images/trustmark.jpg" alt=""></a>
</div>


The above seems to sort the position jumping, but some CSS adjustments may then be needed regarding any changes in the appearance.
