Raphael, Many, many thanks for orchestrating this. One of these tips have bothered me for some time Raphael Quinet wrote: > The layer named "Background" is special.

This jars the ear with a non sequitur, for you tell me I cannot add transparency and then proceed to tell me how to do it. I recall being dumbfounded the first time I read it. Months later, having shed some naivity about transparency, I find it still reads oddly (in English, at least). I propose a less contradictory lead-in phrasing. The "Background" layer lacks transparency. This is why it does not accept layer masks and remains "anchored" at the bottom of the layer stack, a backdrop for transparent layers. But you may add transparency to the Background by right-clicking in the layers dialog and selecting Add Alpha Channel." My two American cents. Be good, be well Garry
