[Moo] stop loading image in dom ?

[brook]

this probably seems like a silly question. but i promise it would be
useful to me...

is it possible to stop an image from loading?  in other words if in my
dom i have

                   <img id="dumb" src="imagename.jpg">

i want to do something like

                   document.id('dumb').stopLoading()

and later on if it turns out i need to

                   document.id('dumb').load()

ideas?
thanks,
brook
