When using a Regexp in the white list, ‘A` and `z` are automatically added to the Regexp expression, also case insensitive.

Returns

NilClass, String, Regexp, Array[String, Regexp]

a white list of extensions which are allowed to be uploaded

def extension_whitelist
  %w(jpg jpeg gif png)

def extension_whitelist
  [/jpe?g/, 'gif', 'png']
end
