Sale price and baseprice in same category layout

[apelius]

Hi!

I need to do the following but i can't figure it how...

In the category layout and the product details layout;

If the product on sale, I want to show saleprice next to product image with the  star background. I also want that the original price is displayed too that the customers can see that how much is the original price.

Of course when the product is not on sale, the sale background is not visible.

I have the demonstration in attachments.
