[1] pry(main)> require 'simple_images_downloader'

[2] pry(main)> SimpleImagesDownloader::Configuration.configure do  |config|
[2] pry(main)*   # You must use RFC 1341 - MIME (Multipurpose Internet Mail Extensions) format
[2] pry(main)*   config.valid_mime_types = %w(image/png image/jpg image/jpeg)
[2] pry(main)* end
