[Smush Pro] Smush PRO setup

Hi there.

I have few questions about SmushPRO:

– How can I restore original images if I choose to make a backup of theme before smushing?

– I have almost 80.000 old images to smush. How can I bulk smush them? Do I have to keep window browser opened and connected for all the time?

– I have an external CDN (cdn77). Is it useful or it’s better to use Smush CDN?
