Disable addtocart button for selected availability text

[stawebnice]

Hi,

please is there a way to hide addtocart button for certain availability - e.g. availability text "Sold out" or image sold-out.jpg (custom) while preserving the settings that things that have stock 0 can be ordered...

I need to solve only some products in the eshop like this, they want to keep the popular sold out products in eshop because they bring traffic and show alternate products on their page, but still not allow these sold out products to be ordered...
