REVIEW

67 links, 1 buttons — all OK

4 image-only link(s) without alt text

Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.

Why this matters

Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
