Image specifications checklist

This is a quick checklist of the images needed for your platform.

For a more in-depth look at all content assets (text, images, videos, and files), see our guides for each content type.

Each image is listed as required or optional. But, if you aren’t using that feature or content type, you don’t need to provide images for it. Or you have special configurations or images that aren’t listed, your JUNO team representative can help!
