Millisecond Forums

Hi! 
I'm new to Inquisit and I'm having some problems with pictures.
I want to show participants the picture of a star saying "+50" everytime they gain extra points in my game. If possible I want to let the star appear on the screen - I'm thinking of some kind of powerpoint like animation. 
Since I didn't know how to insert a powerpoint animation into my script,  I was thinking of simply letting the picture appear for only 2 seconds. I just can't figure out how to do that. This is my situation: I got an openended element and I want to show a picture for the duration of only 2 seconds on that openended element. I guess it's a simple function that I just cannot find. :/ If someone could tell me how to let the picture appear (fly in) on the openended element (again, only for 2 seconds), that would be even better!
Would be great if you could help me out! Thanks a lot. :)
