I had a colleague that wanted to use the Promoted Links webpart on his site as a navigation tool, but he wanted it to display vertically instead of horizontally. So I did some digging around.
Fantastic article!! In minutes, using the tips in this article I was able to make the tiles appear vertically as well as being able to make them appear in rows. I could also resize the tiles, getting exactly the look that I wanted. Check it out and try it for yourself!
