Image
v::image()
v::image(finfo $fileInfo)
Validates if the file is a valid image by checking its MIME type.
v::image()->validate('image.gif'); // true
v::image()->validate('image.jpg'); // true
v::image()->validate('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 PHP extension.
