# Prioritize loading critical images
The Largest Contentful Paint (LCP) is often an image—prioritizing its load can improve LCP by 20-40%, directly impacting Core Web Vitals and SEO.
## Quick Reference
- Use fetchpriority='high' on LCP images
- Preload hero images in document head
- Remove loading='lazy' from above-the-fold images
- Critical images directly impact LCP Core Web Vital
## Check
Identify which images are critical for initial render and ensure they load with high priority.
