Changing the video background image
Rather than displaying a preview image from the video, the video box on your site will instead display a specific static image for a cleaner layout.

To change this image, you will need FTP access to your server. You can replace the image directly with your own, or use custom CSS to override the chosen image.

To replace the image directly:
Connect to your server via FTP.
Navigate to the demo folder in the theme's image folder; this is usually in "wp-content/themes/University/images/demo".
Find the image named college.jpg; remove it, and upload your own image with the same name (remember it must match the name exactly; "college.jpg").
To replace the image via CSS:
Open your University>Template Options section in the left menu.
Click on the "Advanced" tab.
Enable the "Use the override.css file" option and save settings.
Connect to your server via FTP and navigate to the theme's CSS folder; the path is usually wp-content/themes/University/css".
Download the "override.css" file from this folder and open it with the code editor of your choice.
Add the following code to the end of the override.css file, where the URL points to the image you wish to use for the background:
.box.gk-video {
background-image: url('your image link here');
}
Save the changes to the file, and reupload back to the css folder on your server.
The image is now changed.
