Start an Xvfb (X11 virtual frame buffer) server in your remote ssh 
session. R will then use that as an X11 device to produce the PNG 
output. If you are running in a hostile network environment, consider 
using authentication and/or switching off network access to the Xvfb 
session - see the man pages for Xvfb. Xvfb is installed by default on 
most recent Linux distributions - if not, there should be an installable 
package available for it for your flavour of Linux.
