I am presently by using this template during my joomla site and that i have no idea why i can not begin to see the background image. i attempted with ie , opera and chrome and that i attempted to edit web site style sheet however i still cant begin to see the background image, so what can I actually do?

Without supplying every other info or perhaps a direct link i can not assist you to.

Anyway attempt to change permission on template folder to 775. If you cannot access directly via ftp, use a component like ninjaxplorer (it's free) and continue templates/yt_expo and alter permission on folder/subfolder and files.
