Yes, I'm using Windows 7 but also have a Windows 10 machine that I will have to start making more use of soon.
Thanks for all your help

@leocg

But I've clicked "Check for update" several times and it keeps saying "Opera is up to date"

What version do I need and how do I get it?

@leocg
From opera://about/

Version:95.0.4635.90
Opera is up to date

@leocg Right-clicking gives me these options...

...and when I choose Edit, I get this screen only...

Is there anybody out there who can build an add-on so that I can change the images that are shown for each of my shortcuts on the Start page, e.g. for the BBC Weather website, I'd like the "Sunshine and Showers" icon, rather than just "BBC.co.uk":

Thanks,
Dave.
