You'll need photoshop.
For your purposes, duplicate the background layer by grabbing that background layer with your mouse and dragging it down to the very bottom of the layers pallette and drop it over the icon that looks like upturned page thingie-looking thing. Then go up to where it says blend modes on the top of the same layers pallete and with the duplicated layer active, click on the drop down menu and you'll see hard light, choose that, or choose overlay if you want. experiment.
if you want to make it look really cool, filter the duplicated layer with gausian blur of a few pixels in strength.
