Remote image

When building a site that leverages 3rd party APIs with images, you don't want to store those images locally, but still, be able to use all the goodness
of Drupal's field system.

Therefore this module provides a custom field type, which allows you to store the URL to the image, as well as a formatter to render out the field using an image tag.

The remote image module allows us to use images via URLs, but still, renders out the image URL as an image. It provides a new field type 'Remote Image' which you can add in any of your entities to provide users a feature of just supplying the image link instead of uploading an image. The users also get control of the alternate text, title, and height/width of the image. It is
useful in scenarios where image data of your website is stored on a different server and is accessible via a URL. It currently doesn't support applying image styles to images placed using a remote image field. Along with a default formatter, it also provides a formatter that displays meta information of the image as well.

Modules with similar functionality:

Imagecache External: It provides a formatter which can be used to display external images and it also integrates with Image Styles.

Media Remote Image: It provides a media type for remote images and all possible benefits which you get by using media modules.
