Need high res digital file of Carbonite Freezing Chamber

I am putting together my "Triptych" of lifesize Boba Fett, Han Solo in Carbonite, and Darth Vader and want to use the Carbonite scene in the attached picture. I plan to make a print that is 10 ft tall and 16 ft wide, so I need the highest resolution pic possible to send to the printer.

I found this picture on the Star Wars WIkia. It is 2000 x 1350 pixels. Does anyone have a higher res version? I've google'd images a lot and found one 2754 x 1860 pixels, but it looks like a blow-up of the 2000 x 1350 version.

I prefer the same basic scene as Boba Fett, Han Solo, and Darth Vader will all be standing in front of it.

A super high-res screen capture from SWO may work as well.
