Some test image files are from [image-size](https://github.com/image-size/image-size). Many thanks

```

```rust
use imageinfo::{ImageInfo};

fn main() {
    match ImageInfo::from_file_path("images/valid/bmp/sample.bmp") {
        Ok(info) => {
            println!("  - Ext       : {}", info.ext);
            println!("  - Full Ext  : {}", info.full_ext);
            println!("  - Size      : {}", info.size);
            println!("  - Mimetype  : {}", info.mimetype);
            println!("  - Entries   :");
            for size in info.entry_sizes.iter() {
                println!("    - {}", size);
            }
        }
        Err(err) => {
            println!("  - Err       : {}", err);
        }
    }
}
```

Pretty easy?

Don't be stingy with your star : )
