We'll create fresh WordPress site with Attached images title editor installed. You have 20 minutes to test the plugin after that site we'll be deleted.
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.
