It isn't a big deal since those links are all 404. However, it would probably be best to check it out and clean/removes those files.
EDIT: I would highly recommend you do not click those links. I get a pop-up from Norton "A recent attempt to attack your computer was blocked." from each link.

Thanks for the heads up. It looks like those images have already been deleted. I recall a similar incident with images giving users this kind of alert but I'm not getting anything on Avast. Norton isn't really the most reliable anti-virus program out there and has been known to falsely label files as threats.
EDIT:: I will consult the staff and we will likely delete these projects. In the meantime, if anybody else gets an alert, link to the page and take a screenshot.
