Probably something quite simple, haven't got the time to work it out.
My blog images (the main image inserted via the Add-Ons tab) is being resized, they didn't used to.
Old Blog Post - correct image size - https://www.digitalsave.co.uk/samsung-galaxy-x-launch-2018.html
New Blog Post - incorrect image size - https://www.digitalsave.co.uk/red-dead-2-pc-release-date.html
Thanks
