Can you help and guide me on how to optimize the images that users upload on my site?, and how to serve scaled images?.
I used the GTmetrix to test my site and the result before uploading photos, the site was fairly good (page speed score = 89, fully loaded time = 3.9, page size = 985 KB)
after uploading some photos the speed significantly go down (check the attached).
Thanks and best regards.
