Unfortunately, you can't move the caption location. You can move the tool bar within the image borders... You have the option not to show the caption from the tool bar (cogwheel icon).
If you only want to check a caption without leaving the full view, you click on the tool bar ('i' icon) to display the information panel on a given image.
