핵심
Media problems are rarely isolated. A hero image without dimensions can shift layout; an image without alt text can block accessibility and weaken visual understanding.
어떻게 동작하나요
FixWeb records rendered image elements, alt attributes, dimensions, loading mode, fetch priority, and rendered size.
피해 범위
Missing alt text affects screen-reader users; missing dimensions increase CLS risk; lazy-loaded hero images can delay the page's primary visual.

FixWeb가 어떻게 테스트하나요
The rendered DOM snapshot inventories visible images and flags missing alt attributes, weak alt text, absent dimensions, and lazy loading on probable hero images.
확실한 방어
Use an image component or CMS pipeline that requires alt text, emits width/height, generates responsive sources, and treats the first major visual as priority content.
