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.

Your Problem
<ul>
<li>You want to do something inside a post, but a plugin might not exist.</li>
</ul>
Nzymes Solution
<ul>
<li>Insert PHP code into posts’ content easily and safely.</li>
<li>Program features by yourself or trust some of your blog’s authors.</li>
</ul>
<h4>Example</h4>
When citing authors in a post, you’d like to show the number of posts they published. Maybe there is a plugin for that, maybe there is not. Anyway, how difficult to code would it be? Quite easy, actually, given that WordPress has a function to do exactly that (count_user_posts).
With Nzymes, you could cite authors like this
<blockquote>
As you know, {[ =john= | @my.cite(1) ]} and I are very good friends.
</blockquote>
Which could be shown like this
<blockquote>
As you know, John (42 posts) and I are very good friends.
</blockquote>
With Nzymes, many things are just a couple of PHP lines away.
<ul>
<li>Why not display “(42 posts)” in red?</li>
<li>Why not link “John” to John’s posts?</li>
</ul>
<h4>At a glance</h4>
Nzymes injections are expressions like this: {[ enzyme-1 | enzyme-2 | … enzyme-N ]}
<ul>
<li>Nzymes automatically filters title, excerpt, and content of a post looking for injections.</li>
<li>For each found injection, it orderly replaces each enzyme with its value, left to right.</li>
<li>Then it replaces the value of the last enzyme to the whole injection.</li>
</ul>
