Using Sporty template- how to get rid of mountain bike

Hello-
I have been working with the Sporty template.

There is a stock photo image of a mountain bike in the background. I think it is under Wrapper 2 but I could not find any background image. CSS changes do not seem to do anything in TC or on the live site.
If I delete wrapper 2 the image also disappears. So I thought I would just drag in an new Wrapper to that same place... but the mountain bike image comes back too.

Does anyone know where that image is coming from and how to get rid of it or replace it?
thanks.

Hi
this is in the "wrapper2", as "container" styles >> background image
you can change it here

Thank you for your speedy reply.
Maybe I need new eyeglasses. I *think* I am in the right spot. Please see wrapper2EMPTY... attached.
Is that not correct?

I added an image in that field to show you where it shows up, Wrapper2FILLED

Should I make an appointment with my eye doctor?
I am just playing around at this point so I am willing to reinstall TC CK if you think that may help.
Thanks,
Derek

Image with filled field. I hope you can see them- I had to compress quite a lot.

please check in the "page background" styles instead of "container"
