Good to know

Accurate audits, without misleading promises

ALT text needs human judgment. Empty ALT (alt=””) can be correct for decorative images. The plugin highlights items for review, rather than automatically inserting arbitrary descriptions. It scans stored post content and featured-image metadata; some frontend-generated images and CSS backgrounds are outside the scan.
Frequently asked questions

Questions before installing?

Is WTL – Missing Image ALT Checker free?

Yes. The plugin is free, licensed GPLv2 or later, and requires no paid API or AI subscription.

Does it automatically generate ALT text?

No. You review images and write appropriate descriptions, helping prevent inaccurate or unnecessary ALT text.

Why can “Image Usages Scanned” exceed the number of Media Library images?

One image can be used in multiple posts or featured images. Each appearance is counted as an image usage.

Will a Media Library ALT edit update old Gutenberg images?

Not necessarily. Gutenberg may store ALT in post content. For those images, use Edit Post to update the block safely.

Does the plugin send data to WiseTechList?

No. The audit and edits run within your WordPress website; no external account or tracking service is required.
