Step 1: Open underlying photo. Use the Texture tool to add a "weave" texture, set to blend mode = screen. This creates a nice faded background for the other images.



Step 2: Go to the Overlay tool, choose "Your Own" to add each of your photos one at a time.



Step 3: After adding the photos, drag and resize them to suit your composition.



Step 4: Head over to the text tool to add your title.





And voila!
