            getTracer('image_signing');

            // Function to sign an image

                $tracer->startSpan('signImage');

                // Simulate signing process with sleep
                sleep(2); // Simulated processing delay

                // Log the signing operation
                error_log("Image signed: " . $imagePath . " with signature: " . $signature);

                $tracer->endSpan();
            }

            // Example usage
            signImage('/path/to/image.jpg', 'my_signature');
