Hi alexandru.mircea,
I'm a poor photographer really, with no appropriate equipment. I can mostly advise you to check this thread in our subforum, other lyonnais users might for sure be willing to provide you an interesting (and up to date) shot from the Jardin des Curiosités. Samolymp made several banner attempts, don't know tho if he's been very active lately. I could give it a try myself if I have time, but no decent result guaranteed.
