Lighthouse Test Results

I had a lower score than expected due to poor performance in the category of Largest Contentful Paint (LCP). From what I gathered, this deals with load and render time of the image on my homepage. Looking into the report further, the analysis suggests the following:

"Using a modern image format (WebP, AVIF) or increasing the image compression could improve this image's download size.
This image file is larger than it needs to be (4032x3024) for its displayed dimensions (380x285). Use responsive images to reduce the image download size."
