Cropping multiple images identically - Any idea how I can do this?

[Feek]

I've got about thirty .jpg images which I need to crop exactly the same. I know I can bulk resize them using Preview but it doesn't seem possible to bulk crop them using it.

Anyone know how I can do this? Ideally it would be natively within OS X but if I have to use a third party piece of software then I will.

Thanks.

I found a way using an action in Photoshop.

No. That's a resizer. I can resize within Preview (did you read my actual post?). I wanted to crop and I did it using a bulk action in Photoshop.
