Hi,
Recently we released the Image Zoomer Plugin for nopCommerce 2.80 (http://store.novasoftware.com/products/plugins/image-zoomer-plugin).
This plugin lets customers view a magnified portion of product images upon moving your mouse over it. A magnifying area appears right side of the picture. Customers can toggle the zoom levels by using the mousewheel.
If you need any customzations or any other services, you can access our company's nopCommerce developer page for your reference.
Best Regards!
