How to change <div> position dynamicaly

I'm working on a project where I have to display list of users and when we take mouse over to perticular user name, an image of that user should be displayed on right hand side.
I know I'll have to use javascript. but how would I set position of <div> dynamicaly..?

The result should exactly look like following url
