You have to insert a new default image setting as resource.

use use bevy::render::texture::ImageSettings;
//...

App::new()
    .insert_resource(ImageSettings::default_nearest())
    //...

I don't know if there is a way to define the setting for a single image instead of using the global setting.

With bevy 0.9, we switch to using the ImagePlugin

.add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest()))
