I have a WordPress website with an overwhelming number of duplicate photos—around 1 million files—that are taking up too much space. I need help optimizing and managing these images to reduce file redundancy and improve overall website performance. The goal is to organize, clean up duplicates, and streamline the image library while ensuring the site remains functional. Experience with WordPress photo optimization and handling large volumes of files efficiently is essential. Please provide a solution that works within this large-scale scenario.
