I am looking for a little help on an image upload and reize script.
This beast started out just to upload 1 .jpg file
Resize it to two different sizes - add the name to a MYsql database and spit out the results.

Then evolved - I needed to do .gif also
Then evolved once more to handle .png.

That all worked (Allthough I think it is way more complicated then it needs to be but it works)
Now I would like to be able to upload resize and record all those types to the database but instead of doing 1 at a time on the form I would like to do 5 at a time.

Can this existing code be worked to do that?
I was totally confused getting it to this point so I apologize if it is a mess to get through.

I understood the whole array idea for multiple uploads but couldnt get anything to like that to do the resizing of the individual pics???

[code]
<?php

if(isset($_POST['Submit']))

{
require_once ('../mysql_connect.php'); // Connect to the database.
    $user_id=$_SESSION['user_id'];
    
    

    $size = 300; // the thumbnail height
    $size2 = 150;
    $filedir = 'images/'; // the directory for the original image
    $thumbdir = 'images/t/'; // the directory for the thumbnail image
    $listdir = 'images/tl/'; // the directory for the thumbnail image
    $prefix = 'small_'; // the prefix to be added to the original name

    $maxfile = '10000000';
    $mode = '0777';
    
    $userfile_name = $_FILES['image']['name'];
    $userfile_tmp = $_FILES['image']['tmp_name'];
    $userfile_size = $_FILES['image']['size'];
    $userfile_type = $_FILES['image']['type'];
    if (!($userfile_type =="image/pjpeg" OR $userfile_type =="image/jpeg" OR $userfile_type =="image/jpg" OR $userfile_type =="image/gif" OR $userfile_type =="image/png" OR $userfile_type =="image/x-png")) {
    die ("You can only load .jpg, .gif, or .png images.  Please <a href=\"photogal.php\">try again</a>.");
}

// Check for terms.
    if (!empty($userfile_name)) {
        $i = escape_data($userfile_name);
    
    
            // Make the query.
$query = "INSERT INTO img (user_id, img_name) VALUES ('$user_id', '$i')";
            $result = mysql_query ($query) or trigger_error("Query: $query\n<br />MySQL Error: " . mysql_error());
            if (mysql_affected_rows() == 1)
    
        
        
        mysql_close(); // Close the database connection.

     // End of the main Submit conditional.
     }

I would appreciate any direction anyone can provide.
