I have added my first wallpaper to the Goodies section on this website. It’s a shot of blooming chives which was altered with Aperture 2.1 and Photoshop CS3.
You can get the wallpaper by browsing my Goodies section and clicking on the download link for the wallpaper. The download package also includes a custom folder icon (512px as .icns, .png, .ico) with the Chives wallpaper on it.

Beside that, this image is available for print on deviantArt in various sizes.
