Which update and what version to do it to

[Lynnzer]

Ah, I tried it again and it's looking OK, I think, on 1st inspection anyway. If I copy an image location from any page then open it in a browser it is shown as webp so that works well.
Now to do a lot more tidying up or perhaps do a complete rehash of the whole site.
Thanks for your help everyone. Oh, is there a way to do something similar images using webp for video clips to reduce the file size too? Perhaps converting to html5 but does Xara support that?
