servises images size

Post your website URL so I can take a look?

This is where I first used the theme and the “services” images were larger
https://www.wisteriahomes.com.au/wisteria/

then I redid the website from a fresh install and the “services” images are smaller
https://wisteriahomes.com.au/

I have tried changing the images/thumbnail sizes in wordpress settings, but doesnt seem to make any difference even if I delete and upload the images again

what do you think ?
