How to get thumbnail when Right-click on image

I don't enable thumbnail views on my windows computer, it makes loading folders a lot faster, especially network folders. I also like  to see/edit images when i right click o them. Windows gives you quite few tools to easly edit maange your images but installing XnView Shell Extension for windows explorer makes life a lot easier. You can view/edit/resize your image with one right click!

Have a look at screenshot below and you will see what i mean.
