How do I optimize the images

I was reading your guide on optimizing images:

https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:lscwp:image-optimization

But I have no such page as this one:

Here are the tabs I can see in lscache.. there is no tab called image optimization as said in the above tutorial?

So I can not optimize images with this plugin?
