Any idea as to why this is?

I can give you my url in private to have a look if you want

Thanks!

The way GTMetrix grades this criteria is weird. If you have a few images without dimensions, you will grade poorly, even if 99% of your images are OK. I imagine your avatars are screwing up the page. Maybe try a page without avatars.

You can do avatars and profile pictures, but it's a somewhat futile exercise because there are thousands (for me, at least) cycling through your pages.
