Aging-ish

Paint Shop Pro 7

I've seen this effect quite a few times, but I can't figure out how to do it on my own.

If anyone could let me know how to get those scratches and what not in the background of the image to make it look aged?

The icon I'm talking about is number 1.

Thank you in advance...
