Updated for Lumtera 1.2.2 and Lumtera Pro 1.1.1.
Why does it matter?
An image button (<input type="image">) is a submit button drawn as a picture. Without alt text it is announced only as "button", so people cannot tell whether it searches, subscribes or pays.
Who it affects: Blind and low-vision people using screen readers, people who turn images off to save data, and search engines.
What does Lumtera flag?
<input type="image"> elements with no alt text or accessible name.
Check ID input-image-missing-alt — use it to filter the content report or with wp lumtera issues --rule.
How do I fix it in WordPress?
Add an alt attribute that says what the button does, e.g. alt="Search" — not what the picture looks like.
Example
<input type="image" src="magnifier.svg"><input type="image" src="magnifier.svg" alt="Search">How do I check the fix?
- Update the post. The issue disappears from the Lumtera Accessibility sidebar on the next check, and from the site report on the next scan.
- Turn on a screen reader (VoiceOver on Mac: Cmd + F5; NVDA on Windows is free) and move through the image. You should hear a description that makes sense in context — or nothing at all for decoration.
Find this issue across your whole site
Lumtera runs this check in the block editor sidebar as you write, in the Elementor panel, in Review mode on the live page, and across the whole site in the content report and with wp lumtera scan. You can change its severity or turn it off in Lumtera → Settings.
