怎么从ftp上传图片

import ftplib

def upload_image_to_ftp(host, username, password, local_path, remote_path):
    try:
        # 连接到FTP服务器
        ftp = ftplib.FTP(host)
        ftp.login(user=username, passwd=password)
        
        # 切换到被动模式
        ftp.set_pasv(True)
        
        # 打开本地文件
        with open(local_path, 'rb') as file:
            # 上传文件到FTP服务器
            ftp.storbinary(f'STOR {remote_path}', file)
        
        print(f"文件 {local_path} 已成功上传到 {remote_path}")
    except ftplib.all_errors as e:
        print(f"上传失败: {e}")
    finally:
        ftp.quit()

# 使用示例
upload_image_to_ftp('ftp.example.com', 'your_username', 'your_password', 'local_image.jpg', 'remote_image.jpg')
