Timers and Point&Click

I'm trying to accomplish a sort of interactive presentation. The tutorials I've watched so far aren't addressing what I specifically need to do.

Upon program startup I need to display a block of text. Then a click of the mouse to present an image (img 1). Img 1 needs to be displayed for a specific amount of time then automatically disappear, replaced by another image (img 2) for a shorter duration.

After which Img 3 will appear and I need a (hidden) timer to record the duration from its appearance to the moment a target is clicked on.

These steps are to be repeated several times. What's more, I need durations from every img 3 logged for data collection afterwards.

Can anybody provide any resources or advice on how I can learn how to do this?
