Thanks for the update.  There has been a worldwide shortage of the RB211
engines used on the 747-400.  I heard thirdhand that an unplanned engine
inspection/overhaul was mandated by RR.  This unplanned event created
havoc in the airlines' maintenance schedules which are usually planned a
year or more in advance.  BA was taking engines off aircraft which were
down for maintenance to keep the rest of the fleet flying; originally
these aircraft were not scheduled for an engine removal.  I understand
other operators were similarly affected.  About 2 weeks ago, the
situation resolved itself.

Sounds like the photo you saw was supporting the spare engine effort.
