    Number of Style for Image Added into Post

    When adding an image through the GUI, an HTML element is created:

    <img src=".jpg" 
alt="leaf graphic" 
title="leaf graphic" 
class="alignright size-medium wp-image-3109" 
height="25" width="30"/>

    A sequential 3109 and a style name wp-image-3109 (?) is generated.

    Besides, I cannot find it in any table in the DB (wp_posts, wp_postmeta or any other table). How the next ID must be generated? Is there a WP PHP function returning it?

    Thanks in advance.

    I’m not sure if I understand your question correctly, but...

    In WP any attachment is a post (of attachment type). So 3109 is ID of that post.

    This means, that if you’ll take a look at wp_posts table, then you should find that post and there should be some additional info stored as meta fields in wp_postmeta table (for example sizes of all generated images are stored as meta).

    So the ID of next uploaded image will be the next value of ID column in wp_posts table.
