先上效果图，图片顺序可移动，左移右移调准顺序。
代码是文心一言帮忙写的，自己稍微改造就可以用了。
首先是往左移，也就是从下标1移到下标0 ，下标2移到下标1
var imglist = [‘aa’, ‘bb’, ‘cc’, ‘dd’];

function moveElementBefore(currentElement, targetElement) {
var currentIndex = imglist.indexOf(currentElement);
var targetIndex = imglist.indexOf(targetElement);

if (currentIndex < 0 || targetIndex < 0 || currentIndex == targetIndex) {
return; // currentElement not found or targetElement not found or currentElement and targetElement are the same
}

imglist.splice(currentIndex, 1); // remove currentElement from the list
imglist.splice(targetIndex <= currentIndex ? targetIndex : targetIndex - 1, 0, currentElement); // insert currentElement before targetElement
}

其次是右移，下标0移到1，下标3移到下标4
var imglist = [‘aa’, ‘bb’, ‘cc’, ‘dd’, ‘ee’, ‘ff’];

function moveElement(element, targetElement) {
var elementIndex = imglist.indexOf(element);
var targetIndex = imglist.indexOf(targetElement);

// 检查元素是否在数组中，以及目标元素是否存在
if (elementIndex < 0 || targetIndex < 0 || element === targetElement) {
return;
}

// 移动元素
imglist.splice(elementIndex, 1);
imglist.splice(targetIndex < elementIndex ? targetIndex + 1 : targetIndex, 0, element);
}

项目是uniapp写的，
html代码：

<image :src=“info” @click=“previewImg(item.imglist)” mode=“aspectFill”
style=“width:120rpx;height:120rpx;margin: 10rpx 10rpx 20rpx 0 ;border: 1px solid #ddd;”>
<view @click=“DelImg1(i,key)”>

js代码：
leftArrow(e,i){
this.moveElementBefore(e,this.infolist[e].imglist[i],this.infolist[e].imglist[i-1])
},
rightArrow(e,i){
this.moveElementAfter(e,this.infolist[e].imglist[i],this.infolist[e].imglist[i+1])
},
moveElementAfter(e,currentElement, targetElement) {
var currentIndex = this.infolist[e].imglist.indexOf(currentElement);
var targetIndex = this.infolist[e].imglist.indexOf(targetElement);
if (currentIndex < 0 || targetIndex < 0 || currentIndex == targetIndex) {
return;
}
this.infolist[e].imglist.splice(currentIndex, 1);
this.infolist[e].imglist.splice(targetIndex < currentIndex ? targetIndex + 1 : targetIndex, 0, currentElement);
},
moveElementBefore(e,currentElement, targetElement) {
var currentIndex = this.infolist[e].imglist.indexOf(currentElement);
var targetIndex = this.infolist[e].imglist.indexOf(targetElement);
if (currentIndex < 0 || targetIndex < 0 || currentIndex == targetIndex) {
return;
}
this.infolist[e].imglist.splice(currentIndex, 1);
this.infolist[e].imglist.splice(targetIndex <= currentIndex ? targetIndex : targetIndex - 1, 0, currentElement);
},
