Moving Objects Using Javascript

I want to make some interactions with some images on my site. I want to let the possibility to user of clicking on a 开发者_运维问答image, holding it and then drag it everywhere he wants it on the page. Is this possible using only Javascript, HTML5 and CSS3?

PS: I need it to run on iPhone Mobile Safari

Should be possible. This jQuery Mobile plugin seems to support what you need:

It is possible to implement drag and drop using only Javascript, see here.

However, it is not possible to implement this on mobile safari because it will interpret the drag operation as a scroll.
