use std::fs;

fn main() {
    let image_path = "path/to/your/image.jpg";

    match fs::metadata(image_path) {
        Ok(metadata) => {
            let file_size = metadata.len();
            println!("File size: {} bytes", file_size);
        },
        Err(e) => {
            eprintln!("Error reading file metadata: {}", e);
        }
