请教高手，有关产品大图不能超过500PX的问题。

我在后台设置更过了产品大图的尺寸，但是上传后，还是500PX以内，不能放大。但查看原始图，却是大图来的。请教高手解惑！
我在论坛找到同样有此问题的人，但是按他的方法不行。不知道为何。

我的是最新版本1.4.9.1


以下是我找到的。。。。

Hello,

I would like to have my images popup in the lightbox, up to 1200px.
However, when I put this valus in the settings, it will not show more that about 600px (seems to be the default maximum size).
It works for values under 600px !!

Does anyone know where I can change this??

Thank you

Hello,

I have managed to find the answer to this.
You will need to modify this file...
catalog/view/javascript/jquery/thickbox/thickbox-compressed.js
...right at the very end where it says...

|input|440|40|630|188|try|190|

In my case, I modified this to...

|input|1200|40|1200|188|try|190|

Of course, because the script allows it a padding (top, bottom, left, right), in order to achieve maximum size, you will need to play around with your images a bit.

但是按此方法还是不能实现原始图的尺寸
