48405271c5The `{{name}}` placeholder could represent different things depending on
the state of the Result, and referring to it as `{{name}}` seems
arbitrary. This commit changes it to `{{subject}}`, which is much more
generic and it describes well what that placeholder can mean.

# 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.
