  -q, --quiet...

```

### Programmatic API
Add `image_provider` to your `Cargo.toml`:
```bash
cargo add image_provider
```

Create image provider router:
```rust
use image_provider::{get_images_router, ResizeConfig};

// Create images_provider router
let config = ResizeConfig::builder().build();
let images_router: Router = get_images_router(config);
```

Then you can mount `images_router` to your main router.
