hello the following script i am using to upload pictures to my site can anyone help me make it check if the image exists and if it does tell the user that the picture is already there.

PHP Code:
<?php
$uploaddir = './';      //Uploading to same directory as PHP file

$file = basename($_FILES['userfile']['name']);

$uploadFile = $file;
$randomNumber = rand(0, 9999999999999);

$newName = $uploadDir . $randomNumber . $uploadFile;

if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
    echo "Temp file uploaded.";
} else {
    echo "Temp file not uploaded.";
}

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {

Use the function [Only registered and activated users can see links. Click Here To Register...] from php in an if block to check this.

I don't understand your problem.. you use a randomnumber in your script, so it's not likely that this file exist but you can do it this way:

use a while function where you create a new file name as long as the file with the generated name exists
PHP Code:
<?php 
$uploaddir = './';      //Uploading to same directory as PHP file 

$file = basename($_FILES['userfile']['name']); 

$uploadFile = $file; 

while( file_exists($newName) ) {

    $randomNumber = rand(0, 9999999999999); 

    $newName = $uploadDir . $randomNumber . $uploadFile; 

}



if (is_uploaded_file($_FILES['userfile']['tmp_name'])) { 
    echo "Temp file uploaded."; 
} else { 
    echo "Temp file not uploaded."; 
} 

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) { 

} 
?>

instead of
PHP Code:
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) { 
use
PHP Code:
if ($_FILES['userfile']['error'] == 0) {
