Commented on your site and will say the same here. You are asking people to not only visit your website to download this wallpaper, but also to 'Like' you. Most people dislike being manipulated in that fashion, no matter how nice the wallpaper is. I have sites to promote too and all my wallpapers are uploaded directly here with links back to my own sites. And incidentally - I'm using the Chrome and the Like button didn't even appear on your site.
