Image compression code in PHP

Hi my friend Just test this code if it's works. [PHP] $image = imagecreatefrompng($filePath); $bg = imagecreatetruecolor(imagesx($image), imagesy($image)); imagefill($bg, 0, 0, imagecolorallocate($bg, 255, 255, 255)); imagealphablending($bg, TRUE); imagecopy($bg, $image, 0, 0, 0, 0, imagesx($image), imagesy($image)); imagedestroy($image); $quality = 50; // 0 = worst / smaller file, 100 = better / bigger file imagejpeg($bg, $filePath . ".jpg", $quality); imagedestroy($bg); [/PHP]
