How are you setting the image link? I added an image to a post and selected the image to link to its media file.
In the media library folders when edit the image you see permalink has the number of page image, not the filename of image,
like
Permalink: https://www.mydomain.com/569/
I’m not getting that. On a site running WP 5.0 and Media Library Folders, I uploaded a file to a folder. Then I click on the image and it took me to the Edit Media page where the permalink displayed is the site URL and the image title. I do not think the the plugin is doing anything unusual when it adds an image to the media library.
Υou are right of course Alan!
With your answer, you solved the problem!
I had deleted the Image Title attribute in the Image Seo Settings.
Thank you:)
