  <p>I want to extract the "neededWord" from each of them. As it appears from them, the name of the image is always after the "neededWord" and the changing part in the string is before the "neededWord". The way I thought of is to split the string using the "/" seperator <strong>from right</strong> and take the second element in the resulted QstringList. So how to split from right, or is there a better way to do that?</p>
