Why this matters for the Core Web Vitals, and where to start fixing it

Image count and image weight are the bulk of most pages. Those bytes compete with the LCP image for bandwidth: the browser downloads gallery thumbnails while the hero is still streaming. More images also means more decode work, and decoding is not free on a cheap phone.

Fewer, smaller, later. Cut the decorative ones, right-size the rest, lazy-load below the fold. The format and loading splits in the explorer show where to start.

How do images affect the Core Web Vitals?

Passing LCP barely moves across the range: 83% at one end, 81% at the other. This signal does not separate passing sites from failing ones.
