asking for a lightning picture, help!!!

[santino]

Hi all!

I don't drop in lately because I'm pretty busy with university but here comes my problem:

I need a picture of lightning for a fictional commercial poster. Now I'm asking you guys if you could give me a pic of lightning. I won't use it commercial, it's just for university (it won't be sold etc, just homework). I need it for my graphics professor (he said it doesn't have to be a picture I took). As I don't take picture of thunder I'm lost. I'm really asking for your help.

Here is a example pic of what I would like to get: (the lightning must be a straight line with as less "nerves" as possible):

thanks in advance!
