Cliffie, welcome to TalkGraphics.

If it helps, https://cars.metroworldwide.co.uk/in..._files/651.jpg, is extremely wide.

Also, I do not understand why most of the content of the pages seem to be just images.
e.g., https://cars.metroworldwide.co.uk/in...les/669@2x.png.
You are forcing a download of 150MB taking over 5 seconds.

You need to let text be text. Any google bot failing to find text will never rank your sites.

Come back and ask if you do not know how to recover.

Which version of XWD(P) are you using? It looks recent so you ought to be able to select WebP as your image format, saving lots of bytes.
