推荐答案

[根据我的先前经验]

[From the previous experience of mine]

我认为同时preload或一次加载所有30-40张图像不是一个好主意.因为它使Web服务器非常繁忙来处理请求.互联网连接速度慢的人呢?此外，当您只希望在所有图像都加载后才开始幻灯片放映时，用户可能会或可能不会一直呆在您的页面上，直到所有图像都加载完为止.我建议你做一些类似的事情，

I think its not a good Idea to preload or load all 30-40 images at once. Because It makes the web server very busy to handle the request. What about the people having very slow Internet Connection ? more over when you want your slideshow begin only after all images are loaded, the user may or may not stay on your page until all your the images are loaded. I suggest you do some thing like,

lets assume that your Slide show consists of 40 Images,
Preload the first 10 Images  and let the slide show begin,
when the slide show is in process,
send a Asynch request or what ever and download the remaining content. 

我想这是比一次加载所有图像有效的方法

I guess this is an efficient way than loading all Images at once
