PEASE HELP, I DON’T SEE ANY CHANGES IN FILESIZE

I am using the recent version of WordPress and this plugin. I installed it a few days before.

I have used the correct API key and have done proper settings.

I have also used bulk image optimiser setting which shows that it successfully optimized all old uploaded images. I am not sure if it really optimized it or not as it doesn’t show any change comparison like WP Smush.

Anyways, here is my real issue:

When I upload any new image via media or post editor, the uploaded image has the same size as it was before on the local desktop. There is no “Statistics about the compression results” as shown here: https://github.com/win-site/winsite-image-optimizer/raw/master/assets/screenshot-2.jpg

What’s going wrong here? If there is no change in file size, will it display anything? Please help with this.

Ome more thing-

If I continue to find that this is not helping me with image optimization and I deactivate and delete it, will it have any adverse effect on my images. Do remember that I had run “bulk optimization” option with ” do not save original image” enabled. Does this plugin rename the image or add “pre-fix in the image filename?

I see that the plugin was updated six days before hence I feel that the developer is active with this. So, please help me with these two issues.

Thank you
