Hi Movin
None of these are solutions for me so I rolled back the update to when my images were showing correctly, went to this post https://colorlibsupport.com/t/activello-child-theme/ and downloaded the child theme and edited that to look like my site.
BUT I have been under the impression that a child theme protects the site from being changed by updates however when the child theme is being used and I update Activello it changes the image sizes of the child theme.
Why does it do this?
