Image upload

[webmanUK]

hi all.

I have been asked to update a site developed by someone else and one of the things I have to do is change an image upload facility from one thumbnail image (+ associated full size image) to four images (+ associated full size images)

the current lines in the html are:-

elseif ($_POST['add'] == "stud") {
if ($_POST['addproperty'] != "") {
include ("logoupload.php");
if ($_FILES['logo']['name'] == "") {
$logofile = ("");
}
elseif ($_FILES['logo']['name'] != "") {
$logofile = ("images/property/".urlencode($_FILES['logo']['name']));
}
include ("largeupload.php");
if ($_FILES['large']['name'] == "") {
$largefile = ("");
}
elseif ($_FILES['large']['name'] != "") {
$largefile = ("images/property/large/".urlencode($_FILES['large']['name']));
}

and the code in 'logoupload.php' is:-

<?php
$uploaddirlarge = 'images/property/large/';
$uploadfilelarge = $uploaddirlarge . basename($_FILES['large']['name']);
if (move_uploaded_file($_FILES['large']['tmp_name'], $uploadfilelarge)) {
  echo "Detailed file is valid, and was successfully uploaded.<br /><br />";
} else {
  echo "Detailed file upload failed, using default image...<br /><br />";
}
?>

How would i change the above to handle multiple images?

Any help would be appreciated because I'm not that experienced in PHP.

Thanks all
