invoking "Save Target As" dynamically on an image

Hello

I was wondering whether it is possible to invoke the “Save Target As” option (the one accessed via right-clicking a file) on an image in a page.
That is, if the user clicks on a link/button the behaviour should be as if the user right-clicked an image and chose “Save Target As” (on IE of course), i.e. open the save file dialog.

thanks
