Why Tango Smileys Extended plugin doesn't have an option at it's admin area to change the images storage location to an alternative address (external images directory) like Sociable plugin does since version 3.1?
I have more than five WP installations, so that idea can solve the bandwith problem and give one address for one image at many WP installation, so the guest's browser can cache the images well, and the result is all of the websites can loaded faster.
