Description

I recently took some pictures with my phone, and when I went to upload them to a web service they were upside down for some reason. It turns out that the orientation of an image is stored in the exif data of a photo.

  • To start I made a directory for the fixed images:
    mkdir ~/fixed
  • To fix this, I stripped the exif data:
    mogrify -strip -path ~/fixed images/*.jpg
  • Then flipped the images
    mogrify -flip -flop ~/fixed/*.jpg
