How set the oracle standard dimension for Landing Page

]Summary:

We are currently working on updating the Oracle Fusion landing page customization. As part of this change, we need to update the image displayed on the landing page. Therefore, we require to know the information regarding the recommended dimensions (height and width in pixels) for the image used in the landing page customization.

We’d like to know if it’s possible to add a background image to the Oracle login page. If so, could you please provide the recommended image dimensions?

Additionally, after logging in, is it possible to add a background image to the tiles on the landing page? If yes, we’d also appreciate the relevant image dimensions for that.
