Imageoptim runs third party software. WHY?

Question

webstorm

using GULP I collect the project. I decided to try image compression. googled and found such a satya in it there is such a fragment

Gulp
gulp-imagemin
At the time of writing, there is no Gulp plugin that uses ImageOptim.
Note: The folks at Etsy have found that adding just 160Kb of images to their pages increases mobile abandonment by 12%. If you can't reduce the number of images on your pages, at least optimize them.

ImageOptim as it turned out for gulp already exists. Installed. Set up gulp.

gulp.task('images', function() {
    return gulp.src('./app/view/img/*')
        .pipe(imageOptim.optimize())
        .pipe(gulp.dest('dist/i/'));
});

I try

$ gulp images
[11:24:04] Using gulpfile ~/projects/project/gulpfile.js
[11:24:04] Starting 'images'...

iiii ..... here it flies out they say what to open? I press cancel... repeat... so three times
. The result - for each pass it starts an attempt to open the file 3 times. I got tired of this and decided to tell him PS to open the pictures. And now on every pass it fires PS.
Two questions:
- What for?
- how to get rid of?
I run it in webstorm and attempts to find in the settings where it was registered were unsuccessful.
let me know if anyone has experienced this

Answer 1

What OS do you have?
I did not use this package, but the description says that there is a dependency on the ImageOptim-CLI package, which is not supported on Windows and Linux.
I use gulp-imagemin and imagemin-pngquant

Answer 2

because this is just a wrapper over https://github.com/JamieMason/ImageOptim-CLI

WHAT?
