Need to help to modify this script

[ragrim]

Hi,

 

Ive built a website with an image gallery and when i uploaded it to a webhost i discovered they dont have PDO enabled, so ive tried to change my script to work without PDO but ive had no luck, i was hoping someone could look at my script (which i found on the net) and help me to remove the GDO part from it if its possible.

 

Ive work around it not using PDO but this is the only script i can find to upload thumbnails. any help would be muchly appreciated.

 

<?php


if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$category = $_POST['category'];
$username = $_POST['username'];
$description = $_POST['description'];

$date = date("Y-m-d"); 

$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}

/***  get the image info. ***/
    $size = getimagesize($_FILES['userfile']['tmp_name']);

    /*** assign our variables ***/
    $image_type   = $size['mime'];
    $imgfp        = fopen($_FILES['userfile']['tmp_name'], 'rb');
    $image_width  = $size[0];
    $image_height = $size[1];
    $image_size   = $size[3];
    $image_name   = $_FILES['userfile']['name'];
    $maxsize      = 99999999;

    /***  check the file is less than the maximum file size ***/
    if($_FILES['userfile']['size'] < $maxsize )
        {
        /*** create a second variable for the thumbnail ***/
        $thumb_data = $_FILES['userfile']['tmp_name'];

        /*** get the aspect ratio (height / width) ***/
        $aspectRatio=(float)($size[0] / $size[1]);

        /*** the height of the thumbnail ***/
        $thumb_height = 200;

        /*** the thumb width is the thumb height/aspectratio ***/
        $thumb_width = $thumb_height * $aspectRatio;

        /***  get the image source ***/
        $src = ImageCreateFromjpeg($thumb_data);

        /*** create the destination image ***/
        $destImage = ImageCreateTrueColor($thumb_width, $thumb_height);

        /*** copy and resize the src image to the dest image ***/
        ImageCopyResampled($destImage, $src, 0,0,0,0, $thumb_width, $thumb_height, $size[0], $size[1]);

        /*** start output buffering ***/
        ob_start();

        /***  export the image ***/
        imageJPEG($destImage);

        /*** stick the image content in a variable ***/
        $image_thumb = ob_get_contents();

        VALUES (? ,?, ?, ?, '$description', NOW(), '$filesize', '$category')");
        $stmt->bindParam(1, $image_type);
        $stmt->bindParam(2, $imgfp, PDO::PARAM_LOB);
        $stmt->bindParam(3, $image_thumb,  PDO::PARAM_LOB);
        $stmt->bindParam(4, $image_name);
