Before content will appear on the displays, it must first be uploaded to the Newline Signage library.
All content should be identified by building and panel. Let's say, for example, you are adding an image from a field trip to the HS IMC display, you would name the image "HS-IMC-fieldtrip". It may also be helpful to add the date to further individualize each image. You may also want to number each image when uploading multiples from a single event. "HS-IMC-fieldtrip-2" or "HS-IMC-fieldtrip-3".
To add content, click "Library" in the top menu bar.
