The 2026 Drupal Business Survey is open. Your response will help shape the future of the Drupal business ecosystem.The longdesc attribute is removed by the editor when using advanced image, if it's added to the extended_valid_elements in tinymce.inc it won't get removed anymore. See the attached patch.

ckrinaI'm having the same issue in Drupal 7, in CKEditor.
Any ideas to fix it? Thank you.

twodAdding longdesc there works and the attribute is valid (though not commonly used AFAIK).
The patch was created from the wrong folder (wysiwyg/editors), instead of the root wysiwyg folder, re-rolled it for you.
I did a quick
grep -r longdesc ckeditor, which revealed that the word 'longdesc' is only used in the iframe plugin, not the image plugin, so I guess CKEditor doesn't support it.CKEditor does not use an externally supplied tag/attribute whitelist in the same matter TinyMCE does anyway so we could probably not have changed it.
