-/**
- * Generate metadata for image sizes without creating the actual resized images.
- *
- * This function gets the registered image sizes and calculates the filename for each size
- * using the WordPress convention for size annotation. It then adds this information to the attachment metadata.
- *
- * This function is designed to be added to the wp_handle_upload_prefilter in order to restore the metadata that
- * would have been generated. Becuase the sizes are being suppressed on upload, the actual resized images
- * are not being created, but we still need to add the metadata for the sizes to the attachment. This function
- * should have the effect of pre-generating the metadata for the sizes that would have been created.
- *
- * @param array $metadata      The attachment metadata.
- * @param int   $attachment_id The ID of the attachment.
- *
- * @return array The modified attachment metadata, with added sizes.
