Can a still image be closed other than duration?

Hi, I'm a new user and am working through some basics of a project. Thought I'd post questions here if I can't find ready answers. I'll also do them separately to have it out here for others. ;)

Question:

When I have a still image in a scene, I can trigger it to show for a duration from a hotspot. Once it is displaying for the set duration, can I enable some function so that it will hide when clicked?

I have people looking at pictures brought up after clicking on a hotspot, and I'd like to be able to let them dismiss the image if they are done with it before the set duration time.

Thanks!
