Will this plugin update existing images title, ALT tags, captions or descriptions in the media library?

This plugin will not automatically update existing images’ metadata in the media library. Once you install this plugin, then you have to update the image title, ALT Tag (ALT Text), Caption, and Description manually using this plugin.

I can’t see image ALT, Caption or Description columns inside Media Library

Make sure you have set the ALT tag, Caption and Description visible to the media library by going to the “Screen Options” at the top right corner of the page.

How to bulk edit image metadata

Go to the list view in your media library dashboard, then select the images you want to bulk edit. From the top dropdown menu, select “Edit” and then click on “Apply”. This will open the bulk edit editor. You can set image alt tag, caption and description as needed. The provided image alt tag, caption and description will be set for all the selected images.

How to search for blank or empty alt tag, caption and description?

Go to the list view in your media library dashboard. Keep the search box empty or blank. Select alt, caption or description from the search box dropdown list as you want and finally, click on filter.

I have updated/modified the image titles, ALT tags, captions or descriptions for some of the images, but those images still have the old titles, ALT tags, captions or descriptions where they are attached

This usually happens when the image titles, ALT tag, caption or descriptions have been hard-coded into your pages or posts. In other words, those image metadata are not being called dynamically from the media library database. If your pages/posts have hard-coded image metadata or use a page builder that provides a separate option to add image ALT tags, captions or descriptions, then updating image metadata from the WordPress media library won’t help. You need to go to that specific page or post and need to find out the existing hard-coded image alt tag, and replace them as you need.

Will this plugin update the images URLs or slugs as soon as I modify the image titles?

No, modifying the image titles using this plugin will not update the image URLs or slugs. Only the image titles will be updated, while the URLs or slugs will remain unchanged.
