I'm using this script for multiple image upload, but I want to resize each images uploaded through the form so that the maximum height and width should be 500px, without loosing the proportions. Here is the script:

PHP Code:

while(list($key,$value) = each($_FILES['images']['name']))

        {

            if(!empty($value))

            {

                $filename = $value;

                    $filename=str_replace(" ","_",$filename);// Add _ inplace of blank space in file name, you can remove this line



                    while(file_exists('upimg/'.$filename))

  $filename=rand(1,9999).$filename;

$add = "upimg/$filename";  

                       //echo $_FILES['images']['type'][$key];

                 // echo "<br>";

                    copy($_FILES['images']['tmp_name'][$key], $add);

                    chmod("$add",0777);

            } 


Can anyone please help?

Thanks in advance

do you have gd installed on the server you're working on?
