Can't watch folder img with elixir-tinypng

[Jimmylet]

Hello,

I would like to know how to make the "watch" works on my "img" folder? Here, he won't do it.

My gulpfile.js :

elixir(function(mix) {
mix.stylus('app.styl'), null, {
    use: [autoprefixer('last 7 versions', 'ie8' )]
};
mix.tinypng({
    key: 'MY_API_KEY',
    sigFile: '.tinypng-sigs',
    summarize: true,
})

mix.browserSync({
    proxy: 'ecoleinfographie.app'
});

Thank you very much!

Can you send the full gulpfile, package.json, and file structure?

Yes, thank you for your answer.

I attach the gulpfile and the package.json in a zip file.
Here is my file structure :
