Can you share more instruction please? I have a group inside of a repeater. Trying only display one field in the frontend form for each of the rows in the repeater. I’m able to see the field, but it doesn’t update the row.
To print the image URL instead of ID, replace
wp_get_attachment_image( $image, $size );
with
wp_get_attachment_image_url( $image, $size );
