curious: why the "./"?  Other WebUI components appear to just do
"url('images/closed_window.png')"

I was matching L89. It's probably not necessary in either place.

Could we consider removing the "ntp4_" prefix to the filename?  It's the only
file in the ntp4 directory with that prefix, and since it's already in the ntp4
directory, not really needed.

yes
