My emacs version: GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.34, cairo version 1.17.6) of 2022-09-12

Dashboard version: 20221116.1155

When dashboard-startup-banner is set to an image, dashboard fails to start and shows:

dashboard-choose-banner: Symbol’s function definition is void: image-supported-file-p.

Text banners still work.
