Help with Background picture

Hello there
I'm using this forum to host my Minecraft servers website

Currently I'm having trouble changing the background image, everytime i try to change it to my specified image, the background is always black. I am hitting the save button, and using the proper link the generator gives me.
any ideas??

OH!

I have this ad that says, "play" "download"

VERY CONFUSING to new forum members. How do I get rid of it??

i think this is not possible

To remove ads, you have to use credits.
Administration Panel > Misc. > Credit Management

For the image you could try the following CSS:

Code:

body{
  background-image: url( PLACE LINK TO IMAGE HERE );
}

e.g.

Code:

body{
  background-image: url(http://1dut.com/wp-content/uploads/2011/09/awesome-minecraft-wallpapers-in-HD-1dut.com-20.jpg);
}
