Oh, right, good suggestion, thanks Nathan. Moreover, it can also create thumbnails: http://www.gdal.org/frmt_jpeg.html So the work from QGIS side seems considerably reduced. In the far past, reading EXIF was a bit a black magic, beacuse vendors implemented it with lots of variations, thus many exif readers failed often: does anybody have recent experience, is GDAL driver working in most or all cases? Thanks again.
