Open attachments in new pagina ?

[luckske]

Hi,

I have a question about the attachments, if you post an image it opens the attachment in the same page.
For a lot members on my forum it's really confusing because they closed the page insteed of hit the back button in explorer or firefox.
Is it possible to configurate it in options ? maybe i overlooked it.
I it isn't could you plz help me how i can solve this problem ?

Best regards, Luckske
