HI Marc,

I am trying to retrieve image via function like this:

function mkl_pc_get_order_details_image_url( WC_Order_Item_Product $item, WC_Product $orig_product = null ) : string {
	$merge_saved = mkl_pc_find_merge_url_in_item( $item );
	if ( $merge_saved ) return mkl_pc_force_size_params( $merge_saved );

	if ( $orig_product instanceof WC_Product ) {
		$ids = mkl_pc_collect_merge_ids_from_config_data( $item );
		if ( empty($ids) ) {
			$ids = mkl_pc_collect_merge_ids_from_raw_item( $item );
		}
		if ( $ids ) {
			$rebuilt = mkl_pc_build_order_details_image_url( $orig_product->get_id(), $ids );
			if ( $rebuilt ) return mkl_pc_force_size_params( $rebuilt );
		}
	}
	return '';
}

Where mkl_pc_find_merge_url_in_item() is:

function mkl_pc_find_merge_url_in_item( WC_Order_Item_Product $item ) : string {
	$candidate_keys = [
		'_mkl_pc_composed_image_url',
		'_mkl_pc_cart_image',
		'_mkl_pc_preview_url',
		'_mkl_pc_summary_image',
		'_mkl_pc_merge_url',
	];
	foreach ( $candidate_keys as $k ) {
		$val = $item->get_meta( $k );
		$url = mkl_pc_merge_url_from_maybe_html( $val );
		if ( $url ) return $url;
	}

	$html = $item->get_meta( 'Konfiguration' );
	if ( $html === '' ) {
		$html = mkl_pc_get_item_meta_via_db( $item->get_id(), 'Konfiguration' );
	}
	$url = mkl_pc_merge_url_from_konfiguration_html( (string) $html );
	if ( $url ) return $url;

	foreach ( $item->get_meta_data() as $meta ) {
		$url = mkl_pc_merge_url_from_maybe_html( $meta->value );
		if ( $url ) return $url;
	}

	return '';
}

mkl_pc_collect_merge_ids_from_config_data() is :

function mkl_pc_collect_merge_ids_from_config_data( WC_Order_Item_Product $item ) : array {
	$config = $item->get_meta( '_configurator_data', true );
	if ( empty( $config ) ) {
		$config = $item->get_meta( '_pc_configurator_data', true );
	}

	if ( empty( $config ) ) {
		// DB fallbacks
		$maybe = mkl_pc_get_item_meta_via_db( $item->get_id(), '_configurator_data' );
		$config = maybe_unserialize( $maybe );
		if ( empty( $config ) ) {
			$maybe = mkl_pc_get_item_meta_via_db( $item->get_id(), '_pc_configurator_data' );
			$config = maybe_unserialize( $maybe );
		}
	}

	if ( empty( $config ) ) return [];

	$ids = [];
	foreach ( (array) $config as $choice ) {
		if ( is_object( $choice ) && ! empty( $choice->layer_data->image ) ) {
			$ids[] = (int) $choice->layer_data->image;
		} elseif ( is_array( $choice ) && ! empty( $choice['image'] ) ) {
			$ids[] = (int) $choice['image'];
		}
	}
	$seen = []; $out = [];
	foreach ( $ids as $id ) {
		if ( $id && empty( $seen[ $id ] ) ) { $out[] = $id; $seen[ $id ] = 1; }
	}
	return $out;
}

mkl_pc_collect_merge_ids_from_raw_item():

function mkl_pc_collect_merge_ids_from_raw_item( WC_Order_Item_Product $item ) : array {
	$raw = $item->get_meta('_configurator_data_raw', true);
	if ( empty($raw) ) {
		$maybe = mkl_pc_get_item_meta_via_db( $item->get_id(), '_configurator_data_raw' );
		$raw   = maybe_unserialize( $maybe );
	}
	if ( empty($raw) || !is_array($raw) ) return [];
	$ids = [];
	foreach ( $raw as $row ) {
		if ( is_object($row) && !empty($row->image) )      $ids[] = (int) $row->image;
        elseif ( is_array($row) && !empty($row['image']) ) $ids[] = (int) $row['image'];
	}
	$seen = []; $out = [];
	foreach ($ids as $id) { if ($id && empty($seen[$id])) { $out[] = $id; $seen[$id]=1; } }
	return $out;
}

and mkl_pc_build_order_details_image_url():

function mkl_pc_build_order_details_image_url( $product_id, array $merge_ids ) : ?string {
	$product_id = (int) $product_id;
	if ( $product_id <= 0 || empty($merge_ids) ) return null;
	$merge_str = implode('-', array_map('intval', $merge_ids));
	$base = rtrim( home_url(), '/' );
	return "{$base}/wp-json/mkl_pc/v1/merge/{$product_id}/{$merge_str}/";
}

The result is called in this function:

function mkl_pc_attach_best_image_priority_merge( $item, $config_data, $orig_product, $de_id ) {
	$result = [ 'de_attachment_id' => null, 'en_attachment_id' => null ];

	$merge_ids = mkl_pc_collect_merge_ids( $config_data );
	if ( ! empty( $merge_ids ) && $orig_product instanceof WC_Product ) {
		$merge_url = mkl_pc_build_merge_url( $orig_product->get_id(), $merge_ids, 1280, 1280 );
		if ( $merge_url ) {
			$try = attach_image_to_product_wpml_aware( $de_id, $merge_url, 'de', 'en' );
			if ( ! empty( $try['de_attachment_id'] ) ) {
				error_log( "Attached MERGE image {$try['de_attachment_id']} to DE product {$de_id}" );
				return $try;
			} else {
				error_log( "Failed to attach MERGE image to DE product {$de_id}" );
			}
		}
	}

	$best_url = mkl_pc_best_image_url( $item, $config_data );
	if ( $best_url ) {
		$try = attach_image_to_product_wpml_aware( $de_id, $best_url, 'de', 'en' );
		if ( ! empty( $try['de_attachment_id'] ) ) {
			error_log( "Attached config image {$try['de_attachment_id']} to DE product {$de_id}" );
			return $try;
		}
	}

	if ( $orig_product instanceof WC_Product ) {
		$orig_thumb_id = (int) get_post_thumbnail_id( $orig_product->get_id() );
		if ( $orig_thumb_id ) {
			set_post_thumbnail( $de_id, $orig_thumb_id );
			error_log( "Reused original product thumbnail {$orig_thumb_id} for DE product {$de_id}" );
			return [ 'de_attachment_id' => $orig_thumb_id, 'en_attachment_id' => null ];
		}
	}

	return $result;
}

which is assigned to a variable

$de_att = mkl_pc_attach_best_image_priority_merge( $item, $config_data, $orig_product, $de_id );

tha is then uset to set post thumbnail

if ( ! empty( $de_att['en_attachment_id'] ) ) {
					set_post_thumbnail( $en_id, (int) $de_att['en_attachment_id'] );
					error_log( "Set duplicated EN image {$de_att['en_attachment_id']} for EN {$en_id}" );
				} elseif ( ! empty( $de_att['de_attachment_id'] ) ) {
					set_post_thumbnail( $en_id, (int) $de_att['de_attachment_id'] );
					error_log( "Reused DE image {$de_att['de_attachment_id']} for EN {$en_id}" );
				}

Thank you for your time and have a nice day
