2. Gunakan file lokal - Cocok untuk pengembangan dan pengujian lokal
3. Gunakan encoding Base64 - Cocok untuk gambar pribadi atau skenario yang memerlukan transmisi terenkripsi

# [Metode 1] Gunakan URL gambar yang dapat diakses publik
# Contoh: Gunakan URL gambar publik
img_url = "https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20250925/wpimhv/rap.png"

# [Metode 2] Gunakan file lokal (mendukung jalur absolut dan relatif)
# Persyaratan format: file:// + jalur file
# Contoh (jalur absolut):
# img_url = "file://" + "/path/to/your/img.png"    # Linux/macOS
# img_url = "file://" + "/C:/path/to/your/img.png"  # Windows
# Contoh (jalur relatif):
# img_url = "file://" + "./img.png"                # Relatif terhadap jalur file yang dapat dieksekusi saat ini

# [Metode 3] Gunakan gambar Base64-encoded
# img_url = encode_file("./img.png")
