Sorry guys, after updating and for me has ceased to work with an early posted function, now I use this code, can try:
` /**
* Fast imagecopyresampled by [email protected]
*
*/
function fastimagecopyresampled (&$dst_image, $src_image, $dst_x, $dst_y, $src_x, $src_y, $dst_w, $dst_h, $src_w, $src_h, $quality = 3) {
// Plug-and-Play fastimagecopyresampled function replaces much slower imagecopyresampled.
// Just include this function and change all “imagecopyresampled” references to “fastimagecopyresampled”.
// Typically from 30 to 60 times faster when reducing high resolution images down to thumbnail size using the default quality setting.
// Author: Tim Eckel – Date: 12/17/04 – Project: FreeRingers.net – Freely distributable.
//
// Optional “quality” parameter (defaults is 3). Fractional values are allowed, for example 1.5.
// 1 = Up to 600 times faster. Poor results, just uses imagecopyresized but removes black edges.
// 2 = Up to 95 times faster. Images may appear too sharp, some people may prefer it.
// 3 = Up to 60 times faster. Will give high quality smooth results very close to imagecopyresampled.
// 4 = Up to 25 times faster. Almost identical to imagecopyresampled for most images.
// 5 = No speedup. Just uses imagecopyresampled, highest quality but no advantage over imagecopyresampled.
if (empty($src_image) || empty($dst_image)) { return false; }
if ($quality <= 1) {
$temp = imagecreatetruecolor ($dst_w + 1, $dst_h + 1);
imagecopyresized ($temp, $src_image, $dst_x, $dst_y, $src_x, $src_y, $dst_w + 1, $dst_h + 1, $src_w, $src_h);
imagecopyresized ($dst_image, $temp, 0, 0, 0, 0, $dst_w, $dst_h, $dst_w, $dst_h);
imagedestroy ($temp);
} elseif ($quality < 5 && (($dst_w * $quality) < $src_w || ($dst_h * $quality) < $src_h)) {
$tmp_w = $dst_w * $quality;
$tmp_h = $dst_h * $quality;
// on whatever reason PHP 4.4.8 stopped here.
$temp = imagecreatetruecolor ($tmp_w + 1, $tmp_h + 1);
