How to add a stadium picture ?

[great82]

Hi,
I'm trying to add some stadium pictures to some clubs that don't already have them.

For the moment what I have is just a grey pitch : i.imgur.com/iNlAkLg.jpg

Here is the code I have added to my config.xml :
(709.png is in the same folder, all of that in /graphics/... )

I've emptied the cache, reloaded the theme.... still nothing.
I can't seem to find what I am doing wrong.
Can anyone help me ?

I found out where the problem was....
I was using the club ID instead of the stadium ID.
