Please note that images you get after demo content import can neither be used on a live site nor redistributed. If you want to locate the image sources to buy the license, use image search engine https://www.tineye.com/.
If you want to get images from the demo just for test purposes, we can help you with the import. Provide us with temporary wp-admin access.
Regards
