Thank you Ismael, that’s appreciated – as you noticed I have managed to sort square thumbnails for this purpose, but thank you for the CSS to apply, and will give that a go!
Thanks for coming back to me Guenni007, and appreciate your suggestion. Because I’m not using WordPress to drive the theme/site, I was unable to use your suggestion as-is, as I couldn’t work out where to apply it directly into the CSS, but instead I’ve simply generated square thumbnail versions of the images for use in that particular section.
But, problem solved, and appreciate your time.
That’s brilliant, thank you – problem solved. Really appreciate your rapid help!
