Hi Roberto, thanks for your reply.
My point is that the image reset only works with images not served from a collection - the original dimensions of the image have to be found from a standalone image and the collection image’s dimensions then manually set to these: the reset image function doesn’t work for collection images, where you might expect it to, since it’s still a selection available from the image settings, regardless of where the image comes from.
The overall point is that collection-served images have ALL (and correct me if I’m wrong), it seems, to either have their dimensions set by manually inputting standalone image dimensions, or the dynamic image placeholder needs to be set to the correct dimensions first by choosing the image manually from somewhere, when it’s then connected to it’s corresponding collection identical image, and this isn’t great for workflow.
