Online Tools for Assignment

Introduce useful online tools that may help to prepare your assignment.


Operverse (previously known as CC search) allows you to search across more than 600 million images with open access licenses from open APIs and the Common Crawl dataset.  You can learn the usage right of the images with the steps below:

  1. Visit Openverse and conduct a search.
  2. Click on the image you would like to reuse. You can then click on the hyperlink under License to learn the usage right.

  3. Alternatively, you can filter the images by Licenses on the sidebar, so that you can limit the results to the images with the type of licenses you want.
