Growing tired of your Windows Phone's lock screen? Looking for a new wallpaper? eMobilez has collected a vast assortment of 480x800 resolution wallpapers (and other sizes) that range from the abstract to cartoons.
All totaled (if my math is correct) the site offers 803 wallpaper images from nine categories. The only drawback is that the wallpapers aren't keyword searchable but you won't grow tired of surfing through them.
Installation is simple. Just find the wallpaper of your liking, download it to your computer and then transfer it to your Windows Phone via Zune. Then venture into settings and change your Lock Screen setting.
