The WordPress Media Library is a great repository to store all of your content. In fact, it’s really the only place you can upload media files to your website. You can upload a wide range of content from images to PDFs to videos and more.

Built-in to the media library a great way to edit images (resizing and cropping) as well as add in the needed alt-tags, captions, and descriptions. This really nice because every time you use that image on your site, it already has ready for you all the additional data to go with it. You don’t have to enter it over and over.

The Media Library can be accessed from just about everywhere throughout the backend of your site. Anytime you have a text box, there should be an “Add Media” button nearby that’ll bring up the media library.

However, advanced functions of the Media Library can only be accessed by going to it directly when you click on “Media” from the left-hand menu in your WordPress Dashboard.

Something to keep in mind when uploading and deleting images from your repository. As with everything in WordPress, it relies heavily on a PHP database to record every bit of content and settings the site relies on. Which means, every time you upload a new image or media file, it’s cataloged into the database with associated information about the file. Attempting to add files or delete files via FTP in the uploads folder skips that process of updating the database catalog of what media files have been uploaded to the site.

That last bit is extremely important to understand when managing your media files via WordPress. Often times, with new installs of WordPress sites (and depending on your hosting company), there is an upload limit for the size of files. I’ve seen a little as a 2MB upload limit. While you would think that a quick and easy work around to that is simply upload via FTP – all your files need to go through the Media uploader in WordPress.
