Here are some websites that offer creative commons images that we can use on ER-Central. Of course if you have your own image, feel free to use that too. Please enter the url for your image in the attribution box in the Text Creation Editor.
Note though that not all the images on these sites are creative commons. If you don’t know what creative commons is (or the difference between various types of creative commons), you can read about it here. But basically people allow others to use their images for free but with attribution.
These are in no particular order.
If you find some more, please let us know.[contact-form-7 404 "Not Found"]
