If you meant you want to add a picture whenever you enter the menu, I think you can do it by
scripting. And If you really want to change the picture based on the events, you could look up some scripting tutorial.
Pichuzilla, many things are possible with scripting, nearly anything is. Point is, that's not a helpful answer at all. "You can do it with scripting" is like saying "You can clean the mess with a sponge". Given, my example is much more common sense.
It could possibly be done using a common event in the start menu's place, that's how my project does it. As for how to get that working however, I don't remember by now. Sorry.
