^Looks like SkyLease was operating it for a Chinese fishing company. Here's what I've gleaned from a search for the N-number.

SkyLease Cargo (GG, Miami Int'l) has signed a long-term charter contract with a Chinese lobster processing firm for regular cargo flights between Changsha Huanghua and Chicago O'Hare via Anchorage Ted Stevens, the owner of the concerned aircraft said in a statement.
Flights will be operated with a B747-400(F) N908AR (msn 28026), owned by LCI - Lease Corporation International, an aircraft management arm of the investment company The Libra Group."
(That didn't last long.)
As to the characters on the side Jetphotos
"This aircraft is operated by Sky Lease Cargo for a fishing company. The Chinese characters mean 'Having fish every year'. Since fish also means savings in China, it symbolizes being rich."
(If you've ever wondered why darn near every Chinese and most Japanese restaurants have a tank full of Koi, that's why.)
