Audit a page's images for SEO and performance — alt-text quality (missing, linked-empty, filename, stuffed, reused), modern formats (WebP/AVIF), responsive srcset/sizes, LCP loading (lazy hero, fetchpriority), CLS-safe dimensions, real byte and pixel budgets read from the image files, and og:image — scored, with ready-to-run conversion commands. Uses DataForSEO for live image-SERP rankings when connected; otherwise audits from page fetch and parsing alone. Trigger when the user says "image seo", "image audit", "alt text", "image optimization", "convert to webp", "convert to avif", or "image performance".
