I would like to display an image whenever users log in to ServiceNow on special days such as Independence Day, New Year, Christmas, Thanksgiving, etc.
The image should appear like an advertisement banner (for example, a celebration graphic) with an option for the user to cancel/close it.
Has anyone implemented this type of functionality? What’s the best approach—using UI Pages, UI Scripts, or another method?
Any guidance or examples would be greatly appreciated!
