TelemetryTV's Media tab allows you to upload and manage your own media files. Using this menu, you can rotate static images.
First, you'll need to upload an image to your Media Repository. A guide detailing how to do this can be found here.
Next, you'll need to select the Media tab from the left toolbar:
One you're viewing your media library, simply highlight the image you’d like to rotate and click on the rotation icon from the top feature toolbar.
You can choose to rotate any image 90˚, 180˚, or 270˚.
