First, it (almost) can't be the files, because they're just compressed archives of pictures (ZIP and RAR). They don't run any code, so there's nothing to worry about on that front.
In terms of the website, I just ran it against a clean, unprotected system and nothing happened, so I'm pretty confident we're safe.
Just a note, though (to offer another possibility and warn a few interested people), a LOT of people have had their browsers hijacked recently by "zero tolerance" CNET's download.com. They've been bundling a lot of malware in their downloads, sadly, in the last few weeks, including in cases where it violates copyright.

Given the popularity of the site, if anybody has downloaded something from them recently, you might want to do some serious investigation.
