I need to know how to put custom winning and losing icons for girlfriend it messes up my whole game?How do I make it to work?

This is a textbook lazy question.

You didn't to into detail about what actually happens when "it messes up the whole game". You didn't go into specifics of what you tried to resolve you issue and why it didn't work. You didn't detail exactly what you are trying to do and why it didn't have the intended effect.

You will find that it is very difficult to get help online if you don't put effort into your question.
