Here is the image of Jessica that I made for the wallpapers. This is a very high-res version of her and should be sufficient for whatever you might want to use the image. It's very important to make sure that you download the image from the gallery and not the image link that takes you to the image alone. Click on the "belongs to" link to the right and then select it from the full gallery. It's the only way Picasa allows you to download the full-resolution file.
