	if(strlen($model) < 4)
		return false;
	//if it's valid
	else

	//if it's NOT valid
	if(is_numeric($price) == '')
		return false;

}

	//if it's NOT valid
	if(($product)=='please_select')
		return false;
	//if it's valid
	else 
		return true;
}


function validateImage($image){
	//if it's valid
	$allowed = array('image/gif', 'image/jpeg', 'image/jpg', 'image/png');
	if(in_array($_FILES['image']['type'], $allowed))
		return true;
	//if it's NOT valid

	//if it's NOT valid
	if(strlen($description) < 10)

Any help?

$_POST['image'] is not defined. i would check if it is defined first:

<?php
if(!isset($_POST['image']) || !validateImage($_POST['image'])):
?>

Are you sure that a file is being uploaded? Check the contents of the $_POST super global...

echo "<pre>" . print_r($_POST, true) . "</pre>";

The script doesn't upload them until the fields and variables are validated first.
