预览大图时图片未刷新的问题 #143

在预览大图时我对图片做了旋转操作，在旋转的事件回调中将该图片旋转后的canvas数据重新赋值到了缩略图数组的img标签的src中，并通过react的state对图片数组重新赋值，将预览关闭后，发现虽然缩略图组件已经显示旋转后效果了，但预览图并没有重新读取该state中images数组值进行展示，还是旧的未旋转的图片。

关闭时，会有 onRotate 回调重置掉，这个操作你可以屏蔽掉。然后第二次打开后你再调用 onRotate 设置回去

关闭时会有onRotate回调？怎么拿到这个回调去屏蔽呢，onClose参数里没发现有这个函数，打印出来貌似是一个普通的点击事件，不太会用呢:flushed:

这样，你 images 图片数组中的地址有变化吗，如果发生了变化，或者强制给个 key 都可以
