Hi Kor, Guust,
Thank you for all your support. Attached you will find an screenshot as an example of my suggestion to help users understand the best approach. For instance, the image in the listing slider looks fine (top-middle of the screenshot), but the same listing image looks cropped in the regular “latest places” images at the bottom-left of the screenshot.
I undestand an image cannot be both square and rectangular shapped unless you crop it or enlarge without keeping the aspect ratio. My suggestion would be to have a different kind of image the user can upload for square and for rectangular aspect because the featured image and the listing slider is pretty much compatible in shape but the squared related or latest places are not.
Also, I still don’t quite understand how the “upload file” custom field for a place (as an jpg) behaves when a user upload an image.
Thanks,
Eduardo
