Here is the third background in the Valentine Theme and in case your wondering, the themes were all made using Paint Shop Pro.

So I guess I'm making a Valentine's Theme series and this would be the second in that series.

Here is another background, this one in honor of Valentine's Day.  If you like these, you can use them by first clicking the image to bring up the full image, then right click and choose "save as background".  You can then make your own Windows 7 Theme by right clicking on a blank spot of your screen, choose personalize and a window will come up with your available themes.  At the bottom will be the option to select a background, just browse to where the background that you saved is and click it, then when your back on the Themes window, click the "save theme" link towards the bottom, give it a name and your done.  I made these backgrounds to fit my laptop, the resolution is 1366x768.
