Help with 'scrolling' images

Hi

I'm trying to re do a company website. On our previous site using 7.0, we have an image on the top of the main page which uses what I think is called parallax scrolling.

It seems that this isn't an option with 7.1 version, but that you can add animation which may in some cases have similar effects? Does anyone know how to trun on animations, the instructions tell me to go through the paintbrush feature but this seems to be non existent in the 7.1 version. I'm using Bryant Hill as my template - although could change this.

Thanks in advance :)
