Redactor II image resizing?
Quoting Brad Bell in a recent thread:


  If you're on Craft 2.6.2950 or greater, it includes Redactor II 1.3.1,
  where they re-introduced image resizing and positioning support.
  
  You'll just need to add:
  
  imageResizable: true, imagePosition: true to whatever
  craft/config/redactor config file your Rich Text field is set to use
  under its settings.


This combined with the mentioned 3rd party plugins creates a bullet proof and front-end friendly setup.
