我正在尝试创建一个具有淡入淡出效果的背景幻灯片，我发现这个脚本可以很好地完成这个：http://srobbin.com/jquery-plugins/backstretch/
我遇到的问题是它会重新调整图像大小，我想禁用/删除它。
这是代码：
/*! Backstretch - v2.0.3 - 2012-11-30

"use strict";
e.fn.backstretch = function (r, s) {
return (r === n || r.length === 0) && e.error("No images were supplied for Backstretch"), e(t).scrollTop() === 0 && t.scrollTo(0, 0), this.each(function () {
var t = e(this),
n = t.data("backstretch");
n && (s = e.extend(n.options, s), n.destroy(!0)), n = new i(this, r, s), t.data("backstretch", n)
})
}, e.backstretch = function (t, n) {
return e("body").backstretch(t, n).data("backstretch")
}, e.expr[":"].backstretch = function (t) {
return e(t).data("backstretch") !== n
}, e.fn.backstretch.defaults = {

我随机尝试重命名“调整大小”，但效果不佳。

我很难理解你的问题，但我仍然不确定我是否理解你的问题，无论如何我的解决方案如果你想要为每张图片保持所有图像的相同尺寸，那就是添加{{1} }和min width值为图像的css样式，如果图像的样式为“img：{}”那么：
min-height不确定，但那是我理解的解决方案。
