Can I use pictures sample from live demo?

Hi, I’m now your new user of wonderful theme boldial.

I think this theme looks good and I did installed and import sample data as following instruction. Then, I hope to use pictures that you did made up with sample in https://themes.ishyoboy.com/?theme=boldial-wp as same. I saw bellow that you did not include images due to license. Is that mean I can’t use pictures that sample site or if I could, can I use that pictures with commercial site?

thanks for read.
