This might be a solution
to modify image.php from wp-pipe/plugins/processors/image
$source_urls[$i] = trim (htmlspecialchars_decode( $source_urls[$i], ENT_QUOTES ));
$filename = preg_replace(‘/[^a-zA-Z0-9\’]/’, ‘_’,basename($source_urls[$i])) . substr( md5( $source_urls[$i] ), – 4 ) . ‘.’ . end( $temp_arr );
for me it’s ok
