I need images creating using my PSD mock-up template

I have this mock-up template

And I want the cushions changing so it looks like this. ( This was a multi colour set of cushions)

Each of these fabrics needs a garden image so for example the first one all the scatter cushions should be a white palm print. There are 4 fabrics.
