Of course this was Photoshop!
Same as I described in post #2 with the addition of using duplicated groups to speed the process.
Took me less than 5 minutes to accomplish.
I arranged the Daisy image manually as described in post #2.
There are 7 individual daisy image layers.
I then placed the 7 daisy image layers into a group.
I used Drop Shadows in layer styles to add depth to both the individual flowers and the Main group of flowers.
