Makeing a picture a layer?

Hello,
I am designing a background for my website. I made a half oval that goes in the top left hand corner of my background. This oval will hold my companys name. Behind the Text layer which is my companys name and on top of the oval layer i want to insert a picture of Lightning. Then give the oval a beveled edge. I figured out how to make the beveled edge but how to insert the Lightning picture is were i'm stuck. Any help would be greatly appreciated.

Thanks,
Brian

just copy/paste the picture, it will become its own layer. and hopefully you know what to do from there, if not just reply back. also if you could maybe provide a jpeg of what you are working with, im a bit confused. it would help me in helping you =)
