What's causing these image sizes to be wrong?
<p>I cannot work out why some of the images on this page are wrongly sized (2 of them appear smaller than the others).</p>

<p><a href="https://www.violinschool.org/video-testing/" rel="nofollow">https://www.violinschool.org/video-testing/</a></p>

<p>I have re-cropped them all to the same size (355x200, ratio 16:9) so there must be something else causing it.</p>

<p>Am trying to check the html and CSS (it's a wordpress site using Toolset Types) to see what might be wrong, but to no avail.</p>
