Might seem like a poor idea, but why not buy some meadow flowers from local garden centre and position them around the hive (put them in the ground)...then pick a good angle to take your own photo. Afterwards you can use the flowers you buy to either put in your own garden, or plant at site of your new hive. Sounds a little long winded, but no copyright issues and you get to keep the plants.
Alternatively, why not get some children (family members ?) to draw some pictures. You may be surprised how effective such drawings can look when presented well (at least I think so, but I suppose beauty is in the eye of the beholder).
