i am uploading image to s3 server and by php i am making a copy of that image on server , if i upload an image of 2.3 mb than the width of image is not coming but if i upload less size image like 26kb than it is showing the width of image so it is able to create the copy .

Burada php benim kodu:

$s3 = new S3(awsAccessKey, awsSecretKey);

        $thumbId = uniqid();
        $thumbId .= ".jpg"; 
        $img = '';

        if($imgType == "image/jpeg"){
            $img = imagecreatefromjpeg($sourceUrl);
        }else if($imgType == "image/png"){
            $img = imagecreatefrompng($sourceUrl);
        }else if($imgType == "image/gif"){
            $img = imagecreatefromgif($sourceUrl);
        }else{
            $img = imagejpeg($sourceUrl);
        }

    echo    $width = imagesx( $img );
        echo $height = imagesy( $img );

görüntü boyutu ile sorunun ne olduğunu söyle lütfen ..

selamlar
