至此弄明白
原图 vold originalFileName
大图 largeFileName
中图 l mediumFileName
小图 s smallFileName

自动缩放图像代码如下：
//copy original image
if (!copy($destination_name, $destination_name_original))
{
$messageStack->add('failed to copy '.$destination_name_original.'...', "error" );
}
else
{
$messageStack->add('Successed to copy '.$destination_name_original.'...', "success" );
} if (!copy($destination_name, $destination_name_medium)) {
$messageStack->add('failed to copy '.$destination_name_medium.'...', "error" );
}else{
$messageStack->add('Successed to copy '.$destination_name_medium.'...', "success" );
if ($data['ImgExtension'] == ".jpg" || $data['ImgExtension'] == ".jpeg")
$im = @imagecreatefromjpeg ($destination_name_medium );
if ($data['ImgExtension'] == ".gif")
$im = @imagecreatefromgif ($destination_name_medium );
var_dump($im);
if ($data['ImgExtension'] == ".png")
$im = @imagecreatefrompng ($destination_name_medium );
list($width_orig, $height_orig) = getimagesize($destination_name_medium );
$width = PRODUCT_MEDIUM_IMAGE_WIDTH;
$height = PRODUCT_MEDIUM_IMAGE_HEIGHT;
if ($width && ($width_orig < $height_orig)) {
$width = ($height / $height_orig) * $width_orig;
} else {
$height = ($width / $width_orig) * $height_orig;
} $im_s = imagecreatetruecolor(PRODUCT_MEDIUM_IMAGE_WIDTH,PRODUCT_MEDIUM_IMAGE_HEIGHT);
$white = imagecolorallocate($im_s, 255, 255, 255);
imagefill($im_s, 0, 0, $white);
if ($width_orig <= $width){
$wpos=(PRODUCT_MEDIUM_IMAGE_WIDTH - $width_orig)/2;
$hpos=(PRODUCT_MEDIUM_IMAGE_HEIGHT - $height_orig)/2;
imagecopy($im_s,$im,$wpos, $hpos, 0, 0,$width_orig,$height_orig );
}else{
$wpos=(PRODUCT_MEDIUM_IMAGE_WIDTH - $width)/2;
$hpos=(PRODUCT_MEDIUM_IMAGE_HEIGHT - $height)/2;
imagecopyresampled($im_s,$im,$wpos, $hpos, 0, 0,$width,$height,$width_orig,$height_orig );
} //imagecopyresampled($im_s, $im, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig );
imagejpeg ( $im_s, $destination_name_medium, 100 );
imagedestroy ( $im );
}

ok。。。。。。。。。。。。。。。。。。。。。。。。。。。到此全部明朗了 lightinthebox 采集商品多图切换也变得非常容易了。

另外给出几个图像操作有用的函数：
imagecreatefromjpeg — 从 JPEG 文件或 URL 新建一图像
imagecreatefromgif — 从 GIF 文件或 URL 新建一图像
getimagesize — 取得图像大小
返回一个具有四个单元的数组。索引 0 包含图像宽度的像素值，索引 1 包含图像高度的像素值。索引 2 是图像类型的标记：1 = GIF，2 = JPG，3 = PNG，4 = SWF，5 = PSD，6 = BMP，7 = TIFF(intel byte order)，8 = TIFF(motorola byte order)，9 = JPC，10 = JP2，11 = JPX，12 = JB2，13 = SWC，14 = IFF，15 = WBMP，16 = XBM。这些标记与 PHP 4.3.0 新加的 IMAGETYPE 常量对应。索引 3 是文本字符串，内容为“height="yyy" width="xxx"”，可直接用于 IMG 标记。
list — 把数组中的值赋给一些变量
imagecreatetruecolor — 新建一个真彩色图像
imagestring — 水平地画一行字符串

imagecreatetruecolor — 新建一个真彩色图像

imagefill — 区域填充
imagecopy — 拷贝图像的一部分
imagecopyresampled — 重采样拷贝部分图像并调整大小
imagedestroy — 销毁一图像
