The base image (I did a little bit of cropping and resized the words) for the main background image can be found here: http://fc08.deviantart.net/fs71/f/2012/202/3/1/exo_m_wallpaper_by_dymiyake-d581tml.jpg
Let me know if you would like to use the toolbar image, and I'll email or share it to you somehow. I don't have it uploaded anywhere at the moment.
