@smooth: Yes, I agree, false accusations can cause a lot of harm.
For me though, when I see photo collections like this I wonder, is that "someone else's work" being claimed as their own (i.e. the work of the original news site to curate the content together)? In other situations where content is reposted in full, there's been some discouragement of the practice suggesting a better approach would be to link to the source, maybe quote a few paragraphs and include some commentary. When it comes to photos... maybe it's different? I don't know. Either way, the source is listed here (though not linked), so I guess it's all good. If the courts do get involved in this stuff, hopefully we can just make adjustments then as needed. :)
