Hi. Is there any source out there (perhaps within the chinese website?) that offers either public domain images or images that can freely be used for any purposes, as long as one cites the author and the licence? (so something like Creative commons licences) I've found this article on Liaonging for example, which is allegedly a bit like Chinese wikipedia. https://baike.baidu.com/item/辽宁号航空母舰#4 It has a bunch of images but their legality does seem to be questionable. Is there any way to confirm that images are indeed free to use?
