2. Right click on add existing item and select the image that you want to use in this example. You can now see the file selected in the Properties list. Select and drag this image file on to the canvas and resize appropriately.

4. Using the select tool, select the object that you want to be the clipping path. In this case, that will be the text path "London". Press and hold Ctrl and select the other object that you want to clip (the Image).
5. With both objects now selected, go to "Object" --> "Path" --> "Make clipping path"
