Wow thank you so much christian, I will do this to all my product images today.
Should I delete the image optimizer plugin? Is that fairly pointless as it is clashing so no need for it??
And is there something I should know about when uploading new images for my shop page? Or will I always need to use the regenerate plugin?

the area is not going full width, I have it set to the same settings as all the other areas. I seem to keep having issues with areas not going full width…
