[Plugin: Custom Field Images] Call question

Question, Im using the new CFI v2.2.3

Im trying to reference a image on a parent page, but call its child image used.

now using “custom_field_image” I get the image to display, but I want to use my own format.
custom_field_image($post_id = '86', $defaults = '');

Tried using “get_custom_field_image”, but I can not get the image to display, do you have any examples?
get_custom_field_image($post_id = '86', $defaults = '', $format = 'html');
