How do I add media (photos and videos) to my site?

Photos

You can add photos to your site by adding them to the media library. The media library can be accessed from your left sidebar menu under "Media."

You can then add them to your posts and pages by clicking on the "Add Media" button and then choosing from your Media Library

Videos 

If you have a video you would like to include to your site, please upload to a third party host like Youtube.com and then using the embed code to display your video on a post or page. The WordPress Media library does not support video uploads.
