I am dealing with hourly Microwave data that are not covering the
whole World in each layer.
To have a decent presentation map of the data, I'd like to get a set
(say 30-50 layers) displayed in one go.
OK I could do it with the png driver in a script (which is what it may
eventually become), but for the sake of knowledge, is there a GUI
option to load a (rather large) set of images in one block without
having to struggle with a cluttered GIS Manager?

Yes, it is my favorite feature. I use it even to find and add one map.
However, there is some issue with many layers in layer manager. If you
load more than 20 (?) layers (maps) only some of them will be
rendered. There were no investigations; maybe it applies only to
vectors. And, of course, it is slow.
Thanks !

Yann,
If I have a large number of layers, I usually do it from a command line or with a script. I done r.patch with over 100 layers in one command ( before I discovered gdalbuildvirt :-))

The opinions I express are my own and are not representative of the official policy of the U.S.Fish and Wildlife Service or Dept. of the Interior. Life is too short for undocumented, proprietary data formats.
yes r.patch is a good alternative, but it means writing to disk etc.
Was more thinking of a display memory thingy.
Been thinking about the virtual rasters indeed, maybe will have a
look, any C code page you could direct me to?
Cheers,
