jquery - 如何调整照片库中照片的大小以减少加载时间？

Question

我在 jquery 中创建了一个照片库，它工作正常，但如果我添加大照片(5mb​​、4300x3000、8mb 或类似的照片)，加载时间将会很长。我是一名摄影师，我所有的照片都超过 5-6 MB。这是代码:http://jsfiddle.net/EChhQ/4/ ...我试图让它在 fiddle 上工作，但我做不到，但你明白了，是 fancybox photogallery jquery: HTML

<a class="fancybox-thumbs" data-fancybox-group="thumb" href="img/activitate1/2008.jpg"><img  id="imgredus" src="img/activitate1/2008.jpg" alt="" /></a>
                        <a class="fancybox-thumbs" data-fancybox-group="thumb" href="img/activitate1/2009.jpg"><img id="imgredus" src="img/activitate1/2009.jpg" alt="" /></a>
                        <a class="fancybox-thumbs" data-fancybox-group="thumb" href="img/activitate1/2010.jpg"><img id="imgredus" src="img/activitate1/2010.jpg" alt="" /></a>

CSS

#imgredus{
max-height:130px;
max-width:130px;
padding-right:10px;
padding-top:10px;
}

但是您会在 jsfiddle 中找到所有内容。那么我应该更改什么以防止加载时间？

Answer 1

使用 CSS 调整图像大小不会有任何不同，因为文件将保持相同大小，并且下载到用户浏览器上所需的时间也相同。

您唯一能做的就是调整请求的实际图像文件的大小。
