Storyline Triggers

HI,

I need a help in triggers.

I have five pictures in a slide. when i click on each pictures, i have triggered it in a way that it will enlarge the picture with some text. ( by creating slide layers).

Now, after the learner clicks on any of the pictures i want them to return back to first screen. There is an options in settings to " Not to hide the slide layers. EVen if i do that the image in the base layer gets hidden because the slide layer picture is bigger than this.

What do it do now?
