 Thumbnail size is set to 400x800.
 Gallery image size set to thumbnail.
 In desktop browser works normally, it loads thumbnail images.
 In mobile view it loads different sizes (the biggest). Bigger than large
 size set in media settings.

 Tested with google chrome desktop on windows, developer mode in mobile
 view (galaxy s5).

 An other thing, I don't understand why it creates additional 2 image sizes
 which are not present in the media settings.
