I noticed that Message-ID:
<42***********************@newsreader.inode.at> from Martin Brunner
contained the following:
It should be very simple (just login and upload) but it should be able
to rezise pictures. You specify a value for the max height and max width
and depending if the hight or width is more the picture will be rezised
so that it fits into the gallery thumnails even if it was taken 90°
rotated.
Is there such a script available somewhere?
Not a gallery script, but my upload script does what you want
