This theme has a built-in image rotator on the homepage, which displays above the three widget areas. It is only displayed if images have been added.
Go to Rotator->Add New and click “Set Featured Image”.
Upload an image, then click “Use as Featured”. The image will automatically be scaled down to 205px tall, so make sure the image is at least that tall.
The ideal width is 307px.
You can specify the image order by using the “Order” attribute in the right column (lower numbers come first).
