I'm trying to achieve a very simple objective which is to magnify an image. After some searching on the net, it seems like most of the js scripts out there required two image ( one for thumbnail size and another one for zoom-ed size). I'm wondering if I am only having one image, is it still possible to achieve the zoom effect? 

I wish to achieve something like this link [jQuery ImageZoom](http://codecanyon.net/item/epic-image-zoom/full_screen_preview/264395?ref=lvraa&ref=lvraa&clickthrough_id=162871776&redirect_back=true) with only one image, of course, in a free edition.
