The problem with using 1680×720 is that there are very few relevant images around with that exact size and I am not familiar with any basic photo editing skills.
I specifically filtered for images on google greater than 2MP and that were wide in aspect ratio so that it would approximately be the same as the recommended dimensions.
This doesn’t just go for the homepage but for all pages on the site.
Could you explain more about using the image with the same aspect ratio? Is this what I should do?
I noticed that when I changed the setting to slider image it did temporarily work and the image looked great but then it seems to go back to the larger image when i refresh.
