Images missing width/height

Why it matters

Without dimensions the browser cannot reserve space, causing layout shift (CLS).

How to fix it

Add width and height attributes to <img> elements.

How Crawlune finds it

Crawlune flags Images missing width/height automatically on every crawl and lists the affected URLs under theImages tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 500 URLs with every check enabled.
