title: How to map images through WP All Import to a gallery field in ACF
body: <p>I'm using WP All Import to import a .csv file into a custom post type. I've used ACF to create custom fields, one being a gallery field. When I'm setting up the import I can see the gallery custom field and it gives me an option to specify a Key and Value.</p>
  
  <p>The gallery field in ACF has the 'field_56b48b711c3a4' for the Key Field. </p>
  
  <p>Anyone got any ideas how to get the images to be mapped to the gallery custom field during the import?</p>
  
  <p>Thanks</p>
