gThumb is an easy to use image viewer which allows you to rotate some images without losing their quality (because of compression methods, rotating an image can result in a loss of quality).

  2. While holding down the CTRL key, select the images you want to rotate

Using the Command Line

Rotating photos using the command line requires the imagemagick package to be installed.

  2. Type one of the following commands and then press the Return key to rotate an image. Replace original.jpg with the filename of the photo you want to rotate and new.jpg with the name you want the rotated photo to have.

    • convert original.jpg -rotate -90 new.jpg - Rotate the image to the left (anticlockwise)

    • convert original.jpg -rotate 90 new.jpg - Rotate the image to the right (clockwise)
