Image Object Selectable with Save cropped image in media library set to No

[malcalevak]

So, I'm probably missing something, but the documentation says the only way to use the tool if you've set "Save cropped image in media library" to "No" is via the "Image URL", but "Image Object" is still accessible.

This is fine (in fact, it might be preferred for me), but it appears to still save a cropped image in the media library.

It looks like the only way to reference both the crop and non-cropped versions of an image (which is what I want to do) are if done via the Image Object or possibly via Image ID, or is there a way to do that via Image URL as well?

Ideally I'd like to be able to have only one image saved, and reference the cropped data, as well as the original image. Does that make sense?

Is that possible, and I'm just doing something wrong?
