Hi nirmaljoseph,

In order the zoom to work in 2.65 it should be placed in the exactly the same classes as in the manual.
The new version for 2.8 has widget integration with css selectors and allows much more flexibility.
As to the zooming - it depends on the size of the picture. The zoom simply uses the original picture when showing the zoom. The Nop Cloud Zoom plugin uses the Cloud Zoom JQuery plugin.

Could you provide a link to your web site, so that we can see what is wrong?

Thanks
