How to properly set up gulp-image-resize?

Question

JavaScript

I want to run a lot of pictures through gulp. Those of them that are larger than 2000x2000 pixels should be reduced to this size.
windows 10x64 I
include gulp-image-resize (pre-installed imagemagick and GraphicsMagick )
the task itself

gulp.task('imgresize', function () {
   return gulp.src('src/img/')
      .pipe(imageresize({ 
        width : 100,
        height : 100,
        crop : true,
        upscale : false
      }))
     .pipe(gulp.dest('build/img/'));
});

Initially, the file structure is like this

after the task is completed:

I don’t understand why an additional img nesting is created and there are no pictures in the build folder
; moreover, if you write the path, it
gulp.src("src/img/*.*")
gives an error

Answer 1

1. Change return gulp.src('src/img/')to return gulp.src('src/img/**/*.{jpg,png}'))
2. Try using imageMagick, not GraphicsMagick (imageMagick: true)
3. Optionally add optimizations with gulp-changed

var changed = require("gulp-changed");

gulp.task('imgresize', function () {
   return gulp.src('src/img/')
      .pipe(changed("build"))
      .pipe(imageresize({ 
        width : 100,
        height : 100,
        crop : true,
        upscale : false
      }))
     .pipe(gulp.dest('build/img/'));
});

Answer 2

you write the path to the folder, not to the pictures...
gulp.src('src/img/**/*.*')
