php开发，请问大家商城图片是如何解决？
情况是这样的。。。

商城中某商品，在前台的设计中，图片大小分为四种类型，即
1.small_pic，就是最小的图，用在下定单，或者侧栏显示
2.list_pic,栏目列表及首页列表展示的图片
3.goods_show_pic,用于商品展示页面的图，利用js可以放大，放大的图就是下面所要说的图，原始尺寸的图片
4.original_pic，原始图片，规定好尺寸，用来被放大

这样的图片，我的想法，是通过原始图片，缩三次，成为三张不同尺寸的图片，跟sina博客一般的

我不知道这样的方法可不可行，还是说，让设计师做好除原始图另外三张图，再分别上传？

大家谈谈自己的创意及做法，谢谢先。。。

------解决方案--------------------

探讨
呃。。。难道大家都是一张图搞惦的？不需要利用程序再生成？

------解决方案--------------------

探讨

呃，大家都理解错我的意思了。。。

之于放大缩小，不是我的问题的重点，这些都是小事情。。

我的问题的重点就是：产品需要图片，图片的格式分为四个类型，就是最小的缩略图，列表图，展示图及放大图

我想问问大家，如果是你们自己来弄这个系统，图片是通过原始图，生成指定尺寸的图片，还是分四次上传所需要的四张图？或者正如大家说的一样，上传一张图，然后通过style样定义图片的大小（这个方法肯定……

------解决方案--------------------
上传一张原图。用程序自动生成多张需要的缩略图。这是比较实用的方法。

若果每次上传都需要传几张照片。那工作量大了点。还要劳烦美工那边动工。实在有失效率呀！
------解决方案--------------------

好吧。当我没说。
------解决方案--------------------
我觉得还是设置尺寸比较省事
------解决方案--------------------
想要高质量的图片肯定需要GD2的resize来裁剪图片，而且单纯用CSS定义的话，小图没什么问题，大图的话会影响整站的加载速度，多几张图片就把你网站搞垮
