The 'end text wrapping' button allows you to control when text stops wrapping around an image so you can create distinct sections of images and text. This is most useful when creating 'rows' of images with text to the right or left, like the examples below:


Without the 'end text wrapping' button, the text and images may wrap around each other awkwardly. Use an 'end text wrapping' divider between each group of images and text. Place the cursor where you want to start a new section.
Tip: The best way to make these sections is to place the images and text in the order you want without aligning the images. Add the 'end text wrapping' dividers between the sections, then align the images left or right.
