This is a sample shopping cart module.  You can just drop the cart onto the page and it creates the Search box.  Click on Find to learn more about this module.  It is very easy to configure and includes integration to several popular merchant accounts.  Each product can have several images (icon, click for larger, etc.). The shopping cart module also supports downloadable products and the purchase of a product can require the visitor to fill out a form.  This is a great way to sell courses or seminars.
