Frontpage Advertisment

In the main page of this template there is a modulo called "Frontpage Advertisment" which contains only this line of HTML code:

<a class="demo-banner" href="#"></a>

This line shows an image that says: "Available on the AppStore". And the color of the image displayed changes base on the color of the template selected.

The question is: How that line link the image to the module, I mean if i like to change the image i want to display, how can i specify the new image? And how can i specify the other images to be displaed base on the color of the template selected.

Thanks.

the class is called demo-banner, and refers to a png file located in each style : e.g style1/demo-banner.png and same goes for style2 and style3....

How can i change the images this class is pointed to?

i just told you ? edit the picture located in /templates/gk_appsite/images/style1/demo-banner.png

and style2 and style3
