I do this following way:

To change all images in a directory to this resolution regardless of
orientation:
mogrify -resize @442368 *.jpg
Hope it helps, Tomas
Careful with mogrify, it overwrites the original image file.
convert writes to an additional file (preserving the original). Some
people like to live dangerously I guess ;-)

Ali,
This I knew. I usually use the GIMP for this manipulation and am glad
to
learn that ...
Happily, it's not too onerous to do this in imagemagick, using the
'display' command.
This will bring up the first jpg in the directory as the start of a
slideshow.
display *.jpg &
Then you can hit the space bar to cycle through the images. '/' or
'\'
will rotate the image that you're looking at, and Ctrl-S will save
it.
And once they're all properly oriented I can use convert's -resize
option to
change all in the same subdirectory.
Much appreciated,
Rich
