Auto-populate Image ALT Tags from Media Library

Auto-populate Image ALT Tags from Media Library

Details
View on WordPress

Automatically populates Alt and Title tags for images featured in posts and pages, pulling directly from the values set in the Media Library. This makes it easy to manage your image metadata centrally in one place (the Media Library). Plugin also supports the ability to override the Alt/Title tag Media Library values by placing an Alt/Title tag directly on the attachment in the WordPress WYSIWYG Editor.

Tag population only occurs when viewing the post or page, and does not occur in the WYSIWYG editor.
