Layered Photoshop collage, 2400 x 1800 pixels. Each photo base, demonstration illustration, background and caption is a named pixel layer. These are pixel layers, not smart objects or live text. Hide the relevant placeholder-art layer. Insert your own photograph immediately above the matching Photo base layer, then create a clipping mask to use that rectangle as its visible area. Reposition and scale the photograph. Hide the caption pixel layer and add your own text layer to change the caption. Keep an editable PSD and export a separate image for sharing.
