If you make your own image based on the idea of a flower and kaleidoscope,... no problems. This has been done before and would not get you in trouble providing you have the rights to the original flower picture.
If you were to pay this guy for a non-commercial use, and then use it for commercial use, it would be the same as if you never paid him in the first place, even if you modify the image.
The only two options I see are to either pay outright for the exclusive rights or build your own, and I would lean HEAVILY towards building your own.
