Within WordPress, it’s actually extremely simple to grab images from another website, and import them into your own installation. It takes just a handful of functions to do so. This can be extremely handy when trying to move content into WordPress from another system.
For instance, on most organizational websites, you’ll find an employee directory; and in a lot of those directories you’ll find photographs of the employees. Should you ever choose to move your employee directory into WordPress, you can easily import the information as posts (most likely a custom post type) and then pull the employee images and add them to WordPress, too.
