Image()
Validates if the file is a valid image by checking its MIME type.
v::image()->assert('/path/to/image.gif');
// Validation passes successfully
v::image()->assert('/path/to/image.jpg');
// Validation passes successfully
v::image()->assert('/path/to/image.png');
// Validation passes successfully
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 validator relies on fileinfo PHP extension.
