responsive_images: {
  dev: {
    options: {
      engine: 'im',
      sizes: [{

package.json

So,

 src: ['*.{gif,jpg,png}'],
      cwd: 'images/',
      dest: 'images/'

Attention to cwd value, it says that my current directory is /images, so whenever he tries to find the value for src, it will search under /images. BUT my files {.png,.jpeg} arent under /images.

Then, all I had to do was to comment the cwd value. And it worked fine!
