Unsplash API Guidelines: Hotlinking Images
All API uses must use the hotlinked image URLs returned by the API under the
Downloads and views are one of the main motivations for many Unsplash contributors. By opening up the Unsplash API to 3rd party applications their photography is seen and used by more users which inspires them to contribute more, new contributors to join, and an even better library for you and your community of creatives.
When displaying Unsplash images in your application, you should use the
urls property returned by the API on all photo objects.
Many endpoints also support returning a custom size for the photo
urls , so if one of the predefined sizes doesn’t work for your application you can pass a custom width and be returned a
urls.custom field with the dynamically resized image.
