Enable image replacement Replace all the image urls from your website with the ones optimized by Optimole.

I usually research a plugin before installing it, anyway, I have not looked at the code but if the statements can be trusted:

https://wordpress.org/plugins/optimole-wp/

… Optimole will replace all of your image URLs with cloud-based URLs. We don’t replace any images on your website. …

and under the page’s FAQ

Will the original images be deleted?

Absolutely No. We use your original images as sources when deliver the optimized images.

If you are using the basic plan I suggest you consider the limits

With the basic plan, you will be able to optimize 1GB of images per month with 5GB viewing bandwidth.

If you are using the premium plan, does the monthly expense not include support?
