At reading file test2.tif (use pseudocolor for visualization), which is available here http://sites.google.com/site/eospansite/dummy/test2.tif (sometimes the direct link does not work, in such a case point your browser to http://sites.google.com/site/eospansite/dummy and find the file, the 3rd one starting from the bottom)
the file info issued by gdalinfo (using QGIS plugin Raster/Information) is different than the one offered by QGIS under Raster Layer Properties/Metadata. The file was created by QGIS plugin Interpolation out of a vector points file in ED50 UTM31N projection. The fact is that the orientation in QGIS is correct, while R follows the info given by gdal and the image is reversed. Note that QGIS states the origin in the NW corner and then sets negative Y resolution. But this is not what gdalinfo reads.
