Apologies if this has been asked before, I have looked through the forums and on Google and nothing has come up so far.

Today I noticed the ALT text field when you click on an image in /admin/settings/files for the first time.

Can anyone point in the direction of how to actually use this in my theme?

I am using the file_img_url filter to get the URL of an image such as

{{ 'image.png' | file_img_url: '100x100' }}

But how do I get the ALT text field from the Files admin page?

I know how to get the ALT on product images and image fields in the Customizer, but I can’t find any documentation relating to getting it for images in the Files admin page.
