Glad it worked. You're welcome.
With images like those, you're going to have to crop off some of the width or height. The easiest way I've found to do this is as follows:
In PhotoShop, GIMP, or online at a site like Sumo paint (my favorite of these -
.: Sumo Paint 2.0 :. ) open the original image, resize it, while maintaining the original aspect ratio (to avoid distortion), to the proper size either width or height (in your case 960 or 800) so that the the other angle is larger than needed. For example, in the first image you posted above (way too small to make a good wallpaper BTW), I'll resize it to 960x1282. Now, copy/paste that whole image into a new, blank image that is the correct size (960x800). move it around to get the part of the image most important centered, and save as your new image.
Here is the result of that test. As you can see, quite blurry due to the original being so small. I hope all this was clear. It's not as tough as I think I made it seem. If you have any questions, ask away!
