To resize a batch of images we need to use a command line tool mogrify this tool forms part of the ImageMagick Libraries

To use the mogrify command line tool we will need to install ImageMagick

After the install locate the folder via the command line where the images are that need to be resized

cd /home/name/myPhotosResized

Type in the following command to resize the images in the myPhotosResized folder to 1280px in width and maintaining the original aspect ratio
