I don't have pics, but it's fairly easy. Ideally, it should be removed from the car first:
Remove top engine cover (just to ease access to the earth connector)
Remove air intake pipe between throttle body and MAF (take care not to split it, and inspect it for cracks)
Unplug 2x multi-plugs from top of throttle body (push tab and lift metal locks up)
Unscrew the earth connection (brown wire)
Remove 4x torx bolts that hold the throttle body onto the intake chamber
There should be enough clearance now to skoosh the t/b out with carb cleaner. Catch drips with a rag. If not, unplug the throttle position sensor plug and/or the throttle cable.
Reassembly is the reverse. Remember the earth wire and TPS plug, or the car won't start/rev respectively.
If your car has the snap-on hose clips (as opposed to screw-on jubilee clips), they can be removed with a flat-bladed screwdriver, and re-attached with a pair of side-cutters. Alternatively, there's a tool made by Laser
that makes it a lot easier
