If the image element has an alt attribute, it will be easier to access and it will be transmitted to people with poor eyesight.

The alt attribute and its value are not described in the event thumbnail images on the following pages.

https://doaction.org/ja/

Isn't alt automatically set by writing like this?

File: class-do-action.php, line 995

<img src="<?php echo $image_url; ?>" />

↓

<img src="<?php echo $image_url; ?>" alt="<?php echo $event->post_title; ?>" />

If so, we will also make a Pull Request.

Thank you for running the do_action base site.
I am grateful!
