The WordPress Media Library is a powerful tool that makes it easy to upload, edit and delete images and other media. Moreover, it allows to filter, select, include media into posts and pages, with caption, description and alternative text, generating the necessary HTML code. Most of times, the WordPress Media Library covers the most common requirements of a site administrator, and we don’t have to add new functionalities. Anyway, in case we’d need to enhance specific features, WordPress provides a number of functions and hooks that enable us to give more powers to the Media Library without the use of 3rd party plugins. So, in this post we will dive into these functions and hooks with four practical examples.
