Overview

Bialty is a WordPress alt text automation plugin.

Bialty adds alt text to images dynamically in the rendered frontend HTML. It does not rewrite the Media Library. It uses SEO and editorial context already present in WordPress, such as focus keywords, post titles, product titles, or cleaned image filenames.

Bialty is designed for site owners who want broad alt text coverage without destructive database changes, bulk rewrites, or external AI APIs.

La version gratuit ne vaut rien
by donerz·1 year ago

La version gratuite est maudite.

Thirst for profit
by alaron·1 year ago

<font style=”vertical-align: inherit;”><font style=”vertical-align: inherit;”>Давним-давно я полінувався написати скрипт, щоб він автоматично вставляв заголовок поста як альтернативне зображення в цей пост. Можливо, я б так і зробив, якби цей плагін не попався мені на очі. Але зараз я помітив, що ця функція стала платною. Ви жартуєте? Вам не потрібно бути технологічним гуру, щоб робити це без плагіна. Дякую тобі!</font></font>

Next code lines will do the same in your functions.php (save 8$ per month Jesus!!!):

function replace_empty_alt_tags_with_post_title($attr, $attachment, $size) {
     // Check if the alt attribute is empty
     if (empty($attr['alt'])) {
         // Get the ID of the post to which the image is attached
         $post_id = $attachment->post_parent;
        
         // Get the post title
         $post_title = get_the_title($post_id);
        
         // If there is a title, replace the empty alt with the post title
         if ($post_title) {
             $attr['alt'] = $post_title;
         }
     }
    
     return $attr;
}

BIALTY Free version doesn’t work on custom post types (CPT)
by Eric Hepperle·1 year ago·3 replies

Two things I absolutely needed this plugin for was identifying and automatically, bulk updating image alt tags for custom post types and top be able to dynamically create the alt text from the filename.

On the “Welcome” splash page, the first thing I see is:

“GET BIALTY PRO TO ENABLE THESE FEATURES:
– Add Post Title or Image Name as Alt Attribute

I thought, “Well, the free version can’t do that, but let’s see what it can do”.

But, then as soon as I’m stepping through the “tour”, and I realize that the free version only works on “Post” and “Page”, but not on any custom post types. I feel duped.

Although, I wouldn’t say that the plugin name is deceptive, it does appear that the marketing department has buried the lede and failed to clearly (not opaquely) indicate that most features WooCommerce sites, News Sites, Directory sites, etc. need are only available in the Pro version.

Also, the fact that there are no YouTube tutorials on how to use this plugin gives one pause.

I’ve got nothing against premium plugins, but it seems like there is definitely something deceptive about how this plugin is marketed. I cant’ quite put my finger on it.

Only PRO for WooCommerce
by dounsa·2 years ago·1 reply

The title of this product is highly misleading, which is entirely unacceptable. The alt text feature for images linked to WooCommerce products is exclusively available in the PRO paid version.

The issue lies in the lack of clarity within the title and the overly extensive plugin description, where this critical detail is conspicuously absent.

While having a paid version is perfectly fine, it is essential to transparently specify which features are accessible in the free version and which are exclusive to the paid one.

Numerous users have pointed out this problem, yet the plugin description remains unaltered, and responses in the comments section seem to dispute rather than address these concerns.

To resolve this issue, please provide accurate information about your product’s features, and the influx of one-star reviews will likely cease.

Way better than competitors

Way better than competitors, so unfair the negative reviews. Keep the good work!
