How do I add a Vignette

[Loopy]

I'm struggling to figure out how to do this. I have a very basic knowledge of Photoshop 7. Can any one give me any pointers please.
oh, and just so you understand my level, I haven't got my head around layers yet.

Thanks

If you had Lightroom it would take all of 2 seconds......

Is it Raw or jpeg?

I don't do layers yet. Raw is uncooked food!
