Forcepoint ThreatSeeker perceives this site as Suspicious
I enjoy picture sites as I am sure others do but I think that the domain should have articles that could be submitted here that people could discuss. Perhaps an article on lazy-loading of images or something along that line? Maybe an article on loading images on lossy networks over http2 vs http3 and then give two end-points to test. The articles could link to the apex of the domain to provide examples.
