Can't change my background picture (I'm a clueless n00b)

[Triiibes]

My CSS advanced is below.

I uploaded a new jpg and changed the name of the jpg in the code below to match it.

BUT

The background hasn't changed.

What am I doing wrong?

THANKS!

thanks for getting back to me

to be clear, the site works fine with the CSS kyle set up for me. I'm using his CSS!

all I changed was the jpg.

but the picture on the site didn't change.

I needed to upload an image to "SIDES"

the css was a red herring.
