Hi, I’d like to work on this issue. I have experience optimizing image-heavy Next.js apps using next/image, implementing lazy loading, blur-up placeholders, and preventing layout shift. I can replace all img tags in the affected components with optimized next/image, add proper sizing, enable blur placeholders, and ensure consistent performance improvements across courses, dashboard, and profile pages while meeting the acceptance criteria.
