Simple example

If you need to resize all images to the predetermined size and compress them.

var gulp = require('gulp')
var $ = require('gulp-load-plugins')()

gulp.task('images', function () {
  return gulp
    .src('src/*.{jpg,png}')
    .pipe(
      $.responsive(
        {
          '*.jpg': {
            // Resize all JPG images to 200 pixels wide
            width: 200
          },
          '*.png': {
            // Resize all PNG images to 50% of original pixels wide
            width: '50%'
          },
          // Resize all images to 100 pixels wide and add suffix -thumbnail
          '*': {
            width: 100,
            rename: { suffix: '-thumbnail' }
          }
        },
        {
          // Global configuration for all images
          // The output quality for JPEG, WebP and TIFF output formats
          quality: 70,
          // Use progressive (interlace) scan for JPEG and PNG output
          progressive: true,
          // Zlib compression level of PNG output format
          compressionLevel: 6,
          // Strip all metadata
          withMetadata: false
        }
      )
    )
    .pipe(gulp.dest('dist'))
})
