Well I guess the first thing you might do is test the trigger voltage on the flash, as it is likely to be around 150v, and some isolation circuit would be in order before it gets near an Arduino. You would also be well-advised to treat the entire flash assembly with caution. It may be encapsulated.

Thanks,
So basically I was thinking to take out the flash unit.
Find these 2 copper contacts that triggers the flash
solider wires then connect to arduino output.
is this gonna work or break the arduino ? i'm really electronic newbie
thanks - never have used a relay before does it matter which / what type of a relay switch ?
would Optoisolator work? https://www.sparkfun.com/products/314
You should short the trigger wires several times with the battery disconnected. If you can see the charging capacitor, you should short that with a resistor held by pliers to completely discharge it.
So I got the flash out and have attached a picture, how can I possibly trigger this using arduino ? :~
question : do I need to have battery for the flash in or i can use arduino 9v source?
A TIP120 isn't a FET, is it?
What voltage did you measure on the flash contacts?
Is it safe to apply that voltage to your transistor (wherever it turns out to be)?

Thanks, yes to all 3 questions.
could you please assist me further ? I'm stuck.
