When I use a normal single file upload form; both of these statements will

if(!empty($_FILES)){
do som checking if its a jpg.
if not exit;
if(isset($_FILES)){
because it IS set and NOT empty.
$_FILES['file_upload_field'] is set, it's got no data, but it IS set.
$_FILES is set because $_FILES['file_upload_field'] exists.
Submitting a blank form sends all "variables" though without actual
(non-default) content.
