modern cameras have sensors about orientation while taking pictures and 
this orientation is stored a jpeg-tag in the image.
some software takes account to this tag and rotate the image according 
to get the correct orientation, other software ignores the tag and 
displays the picture in landscape mode.
if you (lossless) rotate an image the tag may be removed and the image 
is stored in the new orientation. or only the orientation-flag is 
changed. depending on the software.
