Moving and changing order of slides on time line

I have 17 slides(jpegs) that I have placed on time line in random order to make a slide show / video.
Now when I want to move on a slide to its left or right or to replace it with some other slide at a different place for which I drag the pic. The pic is dragged to new place and then comes back to its original position.
In simple words , how do one rearrange the order of pics on time line different from what is on playlist.

Use the cut / paste tools to change locations
