# Image

- `Image()`
- `Image(finfo $fileInfo)`

Validates if the file is a valid image by checking its MIME type.

```php
v::image()->isValid('image.gif'); // true
v::image()->isValid('image.jpg'); // true
v::image()->isValid('image.png'); // true
```

All the validations above must return `false` if the input is not a valid file
or of the MIME doesn't match with the file extension.

This rule relies on [fileinfo](http://php.net/fileinfo) PHP extension.
