I’ve upgraded to 3.0 but I’m not seeing any new settings

First, please be sure that you’ve deactivated AND deleted version 1 or 2 of Image Intense. They cannot exist simultaneously. 

Secondly, be sure that you’ve clear all site and browser cache & cookies and restart your browser. Divi uses browser caching to speed up module development time.  A lot of the code the Image Intense modules use are stored locally on your computer so that there’s almost no delay when working with the modules. It’s likely that your browser has the earlier version of the Image Intense code stored.
