[Mathieu Pellerin]

Etienne,

Here's a few:

Forest Loss/Gain/Extend
(3-band)

Forest Cover Loss (2000-2012)
(4-band, inc. transparency)

Forest Cover Gain (2000-2012)
(4-band, inc. transparency)
http://earthengine.google.org/static/hansen_2013/gain_alpha${z}/${x}/${y}.png

Make sure you set the appropriate number of bands.
