We use this extension to display and manage product classification icons / product badges. It's the only extension that we found has this functionality or anything like it. Features images and descriptions are easy to manage. There is an extra tab when editing a product to assign it's features. There are two lines that need to be added to the view and list templates. The developer has been very helpful adding a bespoke import function for less than the price of the extension and he also added the view customisations at the same time. I highly recommend this extension and it's developer if you need to display icons for you product features. Magento 1.9.1 (was not in the release drop down)
