I just bought Smush Pro and I feel a little unsafe to use

Hey, I just bought Smush Pro and I feel a little unsafe to use the plugin. Today I have 6832 photos on the website and therefore want to be sure to get it right.

I would like some advice on the following check boxes are available in the professional version

PRO FEATURES

Smush original image:

Super Smush images:

Enable NextGen Gallery integration:

Backup Original Images (Will nearly double the size of your Uploads Directory):

Would love to get some good advice from you!

Regards

Conny
