Here's my contribution to the Cataclysm bandwagon. Updates and tweaks will soon to come.
This is a modified nUI layout. It features official images from the World of Warcraft gallery. This has no functionality enhancement to the nUI layout, and only is used for aesthetic enhancement. This is not a standalone addon and requires nUI to work, you can find it here.
Do help me by posting any bugs or graphical errors in the comments box.
Thanks, enjoy.
