This is a task likely better suited to a different tool, such as
Imagemagick (http://www.imagemagick.org/) convert or mogrify.

If all the images are in the same directory, and you know for sure that you
want all of them to be a certain dimension, say 1370px wide, and they are
all JPG files, then you could use the command:

mogrify -path OUTPUT-PATH -resize 1370x *.jpg

That will resize all the .jpg images in the directory to be 1370px wide,
maintaining the same aspect ratio, and saving them to the OUTPUT-PATH.  If
there is already a sub-folder called "output" for instance, then the
command would look like:

mogrify -path output -resize 1370x *.jpg
