Image Optimization

REVIEW

13 images, 0 KB saveable

https://siteorigin.com/wp-content/themes/siteorigi... is missing width/height — may cause layout shift

Set explicit width and height to prevent CLS.

13 images 89 KB

0 oversized -0 KB

13 legacy format

1 missing dimensions CLS risk

Set explicit width and height to prevent CLS.

Why this matters

Image without explicit width/height — browser can't reserve space; CLS jumps when image loads.
