When I build image tags, I always add Image ALTs & Image Titles. A few years ago I worked with Drupal 6. When you added images in Drupal 6 you could add three things:Image ALTs.Image Titles.Image Description.The option to add description to the Drupal API images was taken down with the release of Drupal 7, and also didn't make a comeback in Drupal 8. Therefore my question is:What is actually this tag and does it have any usage today in SEO to Google or any other major search engine (worldwide)?Update:I did see a similar tag by the way under CKeditor: Long Description URL. The CKeditor is a JS library that is vastly used in Drupal sites.
Image description tag, does it have any contribution to SEO today?

Drupal 6's Image Description field was never shown on the page or in any metadata available to users or crawlers, thus there is no SEO impact in its presence or absence as it's never read by anyone.The description field is primarily intended to be used with file fields, in which case it is used as the text of the link to download the file.https://www.drupal.org/node/432846CKEditor's Long Description URL is included in the longdesc attribute.Long Description URL  the web address of an HTML page containing a longer description of the image (longdesc attribute).http://docs.cksource.com/CKEditor_3.x/Users_Guide/Rich_Text/Imageslongdesc is a HTML 4 attribute for linking to the longer description of an image. It's currently unsupported by every browser. Google seems to ignore it and I don't blame them  it's basically never used and when it is it's not implemented right. Googlebot may follow the link, but it's a stretch to presume it will accurately associate it with that specific image. You'd be better off using the recommended schema.org/ImageObject.
