I've got a problem with my Webpack config. After tag had been written, the image appears, but devServer remove all the pictures after styles applications right after page reload. And it wouldn't back until path was added again in tag. See this screenshot video to have a better image of what is happening.

webpack.config.js:

const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')

let mode = 'development'
let target = 'web'
if (process.env.NODE_ENV === 'production') {
  mode = 'production'
  target = 'browserslist'
}

const plugins = [
  new HtmlWebpackPlugin({
    template: './index.html',
  }),
  new MiniCssExtractPlugin({
    filename: '[name].[contenthash].css',
  }),
]

module.exports = {
  mode,
  plugins,
  target,
  context: path.resolve(__dirname, 'src'),
  entry: {
    main: './main.js',
  },
  output: {
    path: path.resolve(__dirname, 'dist'),
    assetModuleFilename: 'assets/[hash][ext][query]',
    clean: true,
  },
  optimization: {
    splitChunks: {
      chunks: 'all',
    },
  },
  devServer: {
    static: {
      directory: path.join(__dirname, 'src'),
    },
    compress: true,
    open: true,
    hot: true,
    port: 3001,
  },
  resolve: {
    extensions: ['.js', '.ts', '.jsx', '.tsx'],
  },
  module: {
    rules: [
      {
        test: /\.(html)$/,
        use: ['html-loader'],
      },
      {
        test: /\.(s[ac]|c)ss$/i,
        use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader'],
      },
      {
        test: /\.(png|jpe?g|gif|svg|webp|ico)$/i,
        type: mode === 'production' ? 'asset' : 'asset/resource',
      },
      {
        test: /\.(woff2?|eot|ttf|otf)$/i,
        type: 'asset/resource',
      },
      {
        test: /\.(js|jsx)?$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            cacheDirectory: true,
          },
        },
      },
      {
        test: /\.(ts|tsx)?$/,
        exclude: /node_modules/,
        use: {
          loader: 'ts-loader',
        },
      },
    ],
  },
}

The problem is solved for me after upgrading my webpack-dev-server version from v3.11.2 to v4.9.1.

Depending on your preview version, there may be some changes to be made to devServer entry in webpack.config.js. See the doc if you have errors.

For this to work, the static directory of devServer should be the same as Webpack's output directory. For the question, it should be dist instead of src.

You may need to use HtmlWebpackPlugin to serve an index.html in the output folder if you are not already.

devServer: {
  static: {
    directory: path.join(__dirname, "dist"),
  },
  // ....
},

I have the same issue. I realised that images that are imported in JavaScript files with import works fine. The problem is coming from images in HTML files, processed with html-loader. I searched a lot, didn't find why this is happening, but here a way to avoid the issue:

Every time you add a new image, stop your development server, run npm run build or whatever the command you use to build your project. Then run npm start. After that, it works fine.
