using ffmpeg on both landscape and portait pics
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm using the following command:
ffmpeg -i port001.jpg -vf "scale=100:-1" /tmp/1/port_converted_100-1.jpg
It is working fine on landscape pics but it automatically rotate the portrait pics.
Any idea how to avoid the rotation?

The exif Orientation tag is ignored by ffmpeg
This is ticket #6945: ffmpeg fails at jpeg EXIF orientation.
Rotate your images before using ffmpeg*
Manually
jpegtran can be used to losslessly rotate images. You can use it manually to rotate or create a script to rotate based on the Orientation tag.
jpegtran -rotate 90 input.jpg > output.jpg
Note that this will strip some of the exif data. If you want to keep it all add -copy all then remove the now incorrect Orientation tag with exiftool:
exiftool -Orientation="" output.jpg
With exifautotran
This tool with automatically re-orient the images according to the Orientation tag:
mkdir images
cp *.jpg images
cd images
exifautotran *.jpg
* If ticket #6945 is fixed then this method will become moot.
Viewing exif orientation tag in JPG image
You can use exiftool to view the orientation:
$ exiftool -Orientation -S image.jpg
Orientation: Rotate 90 CW
$ exiftool -Orientation -n -S image.jpg
Orientation: 6
Now you can scale with ffmpeg
ffmpeg -i input.jpg -vf "scale=100:-1" output
For more fancy scaling see Resizing images with ffmpeg to fit into specific sized box.

Is there any way to know the pic orientation? If there is not, this solution doesn't fit my needs as I don't know in advance what will be the pic orientation. I'm provising service to re-scale any pic no mater what is the orientation.

Now you can scale with ffmpeg
ffmpeg -i input.jpg -vf "scale=100:-1" output
