Most likely this is a known issue, but Sophos blocks the portrait mmr716.jpg because it detects "MAL/HTMLGen-A". I'm not really sure of what it means, but it felt something that should be reported.

Issue with Sophos and a portrait
Malware attached to an image? Is that what that is? How weird...
Mal/HTMLGen-A is the threat name associated with web content blocked by Sophos products using the reputation filtering functionality.
Note: Mal/HTMLGen-A is not detection of a malware payload on an infected machine. Instead it indicates a Sophos product blocking access to a remote website we believe to be either malicious (a site whose sole purpose is to infect users with malware) or compromised (a legitimate site, but one that has been hacked in order to infect or redirect users).
Looks more like a flag that Sophos products use when they think something might be a problem, but aren't sure. I suspect the "redirect" they're worried about is due to the fact that RPoL's portraits are hosted off-site.
