Shops are very popular in the web. Sometimes it is very essential to show a short preview of the products in popup form. This is very helpful. because it prevents users to leave the current page and go to the other one. They see the product, its price and description. If they want to shop it, they can do it easily. If not, they just close the window and coontinue to browse other products. This code is very simple, but utilizes external powerful resources. Just replace everything you want and use it.
