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!

Maximum file size and type for all images

Small image file sizes help your site load faster. Follow these specifications:

Image file size: Below 200 KB unless otherwise specified.
Image file type: .jpg unless otherwise specified. This helps reduce the file size. If you need a transparent background, use .png.
