Hi everyone,
Any ideas how to change this code so I can have a square thumbnails instead of always the same width but different heights?
Thanks

Code:
function CreateSiteThumbnail($srcFile, $destFile, $width, $quality = 100)
{
$thumbnail = '';
if (file_exists($srcFile) && isset($destFile))
{
$size = getimagesize($srcFile);
$w = number_format($width, 0, ',', '');
$h = number_format(($size[1] / $size[0]) * $width, 0, ',', '');
$thumbnail = CopySiteImage($srcFile, $destFile, $w, $h, $quality);
}
// return the thumbnail file name on sucess or blank on fail
return basename($thumbnail);
}
/*
Copy an image to a destination file. The destination
image size will be $w X $h pixels
*/
function CopySiteImage($srcFile, $destFile, $w, $h, $quality = 100)
{
$tmpSrc = pathinfo(strtolower($srcFile));
$tmpDest = pathinfo(strtolower($destFile));
$size = getimagesize($srcFile);
if ($tmpDest['extension'] == "gif" || $tmpDest['extension'] == "jpg")
{
$destFile = substr_replace($destFile, 'jpg', -3);
$dest = imagecreatetruecolor($w, $h);
//imageantialias($dest, TRUE);
} elseif ($tmpDest['extension'] == "png") {
$dest = imagecreatetruecolor($w, $h);
//imageantialias($dest, TRUE);
} else {
return false;
}
switch($size[2])
{
case 1: //GIF
$src = imagecreatefromgif($srcFile);
break;
case 2: //JPEG
$src = imagecreatefromjpeg($srcFile);
break;
case 3: //PNG
$src = imagecreatefrompng($srcFile);
break;
default:
return false;
break;
}
imagecopyresampled($dest, $src, 0, 0, 0, 0, $w, $h, $size[0], $size[1]);
switch($size[2])
{
case 1:
case 2:
imagejpeg($dest,$destFile, $quality);
break;

imagepng($dest,$destFile);
}
return $destFile;
}
