Add A Control Like Picturebox Programmatically And Allow User To Move It?

How to add a control like picturebox programatically and Allow user to move it with mouse? on google but cant find anything. Thats why I am here. In my application user creates a picturebox and a label at runtime by selecting a file from drag drop. User can create as many files he wants. But the problem is that I dont know that how to move both picturebox and label to change their location in a flowlayoutpanel which contains these controls with mouse. I know that how to add a control like picturebox programatically but dont know how to move it. I add picturebox by:

dim picturebox as new picturebox
flowlayoutpanel1.controls.add(picturebox)
