You can download the file directly from my website. I've set up a couple different ways to do this, either via the photo album or a direct link.
I am not an expert on operating systems, so if you don't know how to change your desktop wallpaper, please don't email me - I will indubitably steer you wrong. Your computer's help files will be more concise, more knowledgeable and more responsive than I could ever hope to be.
I've sized this to fit a standard screen height of 768 - I realize there are lots of variables that could impact how the file displays on your screen. Let me know if, once you get the file installed, there are display quality issues (keep in mind, too, that options such as "stretching to fit," "tiling" and "cropping" will impact your display, so check those first!).
Thanks, as always, for following along with my artwork,
