This plugin adds a “Duplicate Attribute” page under Products in the WordPress admin, allowing you to:
<ul>
<li>Duplicate WooCommerce global product attributes</li>
<li>Copy all attribute settings (name, slug, type, order by, visibility)</li>
<li>Copy all attribute terms in the same order</li>
<li>Copy all term meta (e.g. color preview codes, custom fields)</li>
<li>Preserve parent/child hierarchy for terms</li>
</ul>
Perfect if you need to quickly replicate existing attribute taxonomies for new products or stores.

This plugin has the hability to change the title of all the images attached to a post by inserting a new title for them all.
The plugin lists the posts on a table which you can order by name or category and each row has an input field which applies (with ajax), the input value to the title of all the images attached to that post.
This plugin uses Matt Van Andel class (which extends WP_List_Table) to use official WordPress API to create the tables. 
I want to thank @nh3ad who helped me on this development.
