Image from custom field (ACF)

Hello!
I’m trying to setup attachment of custom image from custom field provided by ACF plugin.

– output for field was URL. Name of field was added to your plugin setting.
– output for field was Object. Name and name of field in array [‘url’] was added to plugin.

In both cases settings has no effect, image from field doesn’t appear in post options on post editing page.

What I’m doing wrong?

Best regards, Taras.
