I have an RGB image and a Gray scale image. I would like to merge them in a 4 bands image. How can I do that? Is there a simple way to do it from QGIS or I have to modify the image before to load them in QGIS.Thanks a lot!

Enable the GDALTools plugin (Plugins->Manage Plugins... menu) and use the Merge tool (Raster->Miscellaneous menu) and tick the Layer stack option.

Thanks a lot! But I have this message:Format driver JPEG does not support creation and piecewise writing. Please select a format that does, such as GTiff (the default) or HFA (Erdas Imagine). – G M Jun 28 '13 at 22:06
Ok,now it works, I've selected geotiff as output format. But now I have lost the exact georeferencing. – G M Jun 28 '13 at 22:14
