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

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

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

Make sure you have set 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 meta data

Go to the list view in your media library dashboard, then select the images that 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 you needed. The provided image alt tag, caption and description will be set for all the selected images.

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

This happens usually when the image 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 meta data or using a page builder that provides a separate option to add image ALT tags, captions or description, then updating image meta data from WordPres 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.

Very important plugin, lightweight, does not interfere with your dashboard is not intrusive. It is a must have plugin, why woocommercedoes not have this functionality already offered? I upload products regularly, it was taking me a minute + or so to add alt texts to 30 images, no it takes 10 seconds, which saves so much time for me.
