I have lots of images that has to be uploaded via media library. I want to know, is it possible to add file name to alt attribute field automatically when I am uploading them? At the moment I have to open each image and add the alt attribute manually.

A viable solution I found was adding the post title to images missing the ALT attribute.

Add the following to your functions.php file:

function add_alt_tags($content)
{
        global $post;
        preg_match_all('/<img (.*?)\/>/', $content, $images);
        if(!is_null($images))
        {
                foreach($images[1] as $index => $value)
                {
                        if(!preg_match('/alt=/', $value))
                        {
                                $new_img = str_replace('<img', '<img alt="'.$post->post_title.'"', $images[0][$index]);
                                $content = str_replace($images[0][$index], $new_img, $content);
                        }
                }
        }
        return $content;
}
add_filter('the_content', 'add_alt_tags', 99999);

Alternatively, if you want to replace the attribute with the file name, you could look into using the get_attached_file function for the $new_img variable.

I know I am very late to the party, but I couldn't let this one pass because I wrote a plugin just for this: Auto Image Attributes From Filename With Bulk Updater

As the name suggests, there is a bulk updater as well, so you can update existing images as well.
