Webpack img(image) path error - image

Question

I'm using webpack in my project, there are two images in my project.
the first image path is: /build/img/1.png (The following is called A)
the second image path is /build/img/2.png, (The following is called B)
The two pictures have the same path. but, the A can be displayed on the page, B can not.
my webpack.config.js:
var webpack = require('webpack');
var path = require('path');
var fs = require('fs');
var AssetsPlugin = require('assets-webpack-plugin');
// var assetsPluginInstance = new AssetsPlugin();
// var proxy = require('http-proxy-middleware');
var remotePath = "./__build__/";
fs.readdir(remotePath, function (err, files) {
if (!err) {
for (var i = 0; i < files.length; i++) {
var filesName = files[i];
if (filesName.indexOf("chunk.js") > 1) {
fs.unlink('./__build__/' + filesName);
}
}
}
});
module.exports = {

bundle: "./web_app/index.js"
},
devtool: 'cheap-module-eval-source-map',

Image sequence: React code, project directory, dev Tool
I've merged several images, because stackoverflow rules that I can only publish two links
