Also i'm not sure if you can dynamically display the new image without saving it as an actual physical file somewhere. If you can, I'd love to know how, if anybody knows?

PHP Code:


			
<?php

function thumbnail ($szFile, $intNewWidth, $intNewHeight) {



    $aImg = getimagesize($szFile);

        $intWidth = $aImg[0];

        $intHeight = $aImg[1];

        $szFileType = $aImg['mime'];

    unset($aImg);



    switch ($szFileType) {

        case "image/pjpeg": case "image/jpeg": $imgNew = imagecreatefromjpeg($szFile); break;

        case "image/x-png": case "image/png":  $imgNew = imagecreatefrompng($szFile); break;

        case "image/gif": $imgNew = imagecreatefromgif($szFile); break;

        default: return false;

    }



    $imgResized = imagecreatetruecolor($intNewWidth, $intNewHeight);

    imagecopyresampled($imgResized, $imgNew, 0, 0, 0, 0, $intNewWidth, $intNewHeight, $intWidth, $intHeight);

    if (imagejpeg($imgResized, "temp/temp.jpg", 100)) {

        imagedestroy($imgResized);

        imagedestroy($imgNew);

        return true;

    } else {

        imagedestroy($imgResized);

        imagedestroy($imgNew);

        return false;

    }



} // thumbnail()



$file = "path/to/your.jpg";

thumbnail($file, $_GET['w'], $_GET['h']);

?>



<img src="temp/temp.jpg" />

-m

I have no idea, I know the person who made the site though, all he told me was he kept the aspect ratio the same, though I did that, and it still looks like shit. :P his is better. and he said to do it, was just math. -_- ugh.
