Bulk image resizing and format conversion

All of us download photos from our phones and cameras. Before we e-mail an image or post it to the Web, we may need to resize it or perhaps change the format. We can use scripts to modify these image files in bulk. This recipe describes recipes for image management.

Getting ready

The convert command from the ImageMagick suite contains tools for manipulating images. It supports many image formats and conversion options. Most GNU/Linux distributions don't include ImageMagick by default. You need to manually install the package. For more information, point your web browser at www.imagemagick.org.
