I installed your plugin and use the pro trial period. I have a question about the image optimization.
When I optimized images a week ago, for the first time, I only checked the option "Super Smush my images" that you provide with no option to edit any dimension of images. Now, I am not sure if I needed to check "Resize my full-size images" option, instead. I would like to ask you about how you can sure about the image dimensions on the Super Smush my images option? I recently change my wp template and I have some load time website issues that i think that it has to do with image size files to some extent. I am a little bit anxious about it and I am trying to find a way to solve. Would you suggest me that I go for the second option of your plugin and "Resize my full-size" images? Or is it unnecessary? How can I adjust only the featured image dimensions and not those on the other places in any of my posts? I don't know a lot of things about that, but I think it's crusial for load time.
I also took a look on this: https://premium.wpmudev.org/blog/compress-resize-images-wordpress/
that helped me a little bit to understand some things.
Thank you in advance for your time!
