Not sure if it works

I gave this plugin a go on my website and the moment I activated it all the images have went down. So I am not sure how this works. I was about to buy the lifetime deal for this from Appsumo glad that they have the Trial and I was able to notice this issue at first. I have reached out to their support and let us see what they say. Also since it is from a new brand it is better to test the plugin with the newer version of wordpress and it says it is not tested.
