Implement Server-Side Pagination and Lazy Loading

[FaheemOnHub]

Summary
Our application's home page, which showcases community-generated images, is experiencing performance issues as our user base grows. Currently, we fetch and display all images at once, resulting in slow page loads, high memory usage, and a poor user experience, especially on mobile devices. We need to implement server-side pagination and lazy loading to optimize performance and scalability.

Expected Behavior

Initial load shows only the first batch (e.g., 20) of most recent images.
A "Load More" button or infinite scroll fetches the next batch.
Images are lazy-loaded as they enter the viewport.
Server response times stay under 2 seconds, even at 100k+ images.
No out-of-memory errors or app crashes on any device.
