You could do this layout using linked containers. Create two ContainerControllers. The first one to hold the text that will go to the left of the image, and the second to go below. Use FlowComposer.addController() to add them in to the textflow, and position the containers (Sprites) correctly with respect to the image. The text in the flow will start in the first container, and if there is enough text, flow into the second container.
