Media Library
Each WordPress blog has a Media Library that stores all the additional files (audio, video, images, etc.) included in the website content. To access the WP Media Library, after logging in, click on the “Media” tab, on the left-hand side of the page. To add new media to the library, simply click the ‘Add New link under the “Media” tab, and then select which files you wish to upload.
You can also upload photos or other media directly into a post or page from your computer or other sites. Here’s a short “How-To” video about inserting media into your posts or pages.
