How can you change the ordering of pictures in a slide?

To change the ordering of pictures in a slide, using the Arrange options in the Format Ribbon Tab is the most effective approach. The Arrange group provides various functionalities specifically designed for managing the positioning and layering of objects on your slide. You can bring objects forward, send them backward, align them with other elements, or distribute them evenly, giving you precise control over how pictures are displayed in relation to one another.

This is particularly beneficial when you need to ensure that certain pictures are prominently displayed in front of others or when you want to create a specific aesthetic on your slide. The options available in the Arrange section allow for quick adjustments without having to manually drag and reposition each picture, which can be time-consuming and less precise.

The other methods may allow for some level of adjustment, but they don't provide the comprehensive and refined control available through the Arrange options in the Format Ribbon Tab. For instance, while right-clicking and choosing Order can change the layering of selected images, it does not offer the additional alignment and distribution features that the Arrange options do. Similarly, manually moving pictures in Slide Sorter view doesn't address the need for ordering on the same slide and lacks efficiency compared to the organizational capabilities in the Format Ribbon Tab.
