Hello!
I am currently compiling themes for Windows 7 consisting of the best of the Artwork/Wallpapers available. The themes are being compiled on a variety of topics. These themes are featured on our blog. We have started a gallery of Windows 7 themes here.
One of the categories is TV Series. Plan to use your Dexter Wallpaper in the Theme. For credits, a text file would be provided with the theme, which will give you due credits for your work as well as a link to your profile on DeviantArt. The credits are also given in the Deviation details. Please see my Profile and gallery for details.
I have permission from quite a few DA Artists. Hope you too are alright with this!
PS: Like COD MW2? Maybe you would like this >
