Some times the way the slides are set up just isn't what you want. In this case you may need to move things around.
To chang the position of pictures and text boxes select the item, then click on the border and drag the item to it's new location. I have circled the border to identify it.
In the above picture there are two pictures and one text box that have been moved into their current position.
Next is saving, we don't want to lose what we have done.
