K, here's what I got: Nothing.

But I find that interesting in of itself. The E-Mail is just what it seems on face value. There's nothing throwing any flags that they made any attempt to bounce it through any servers, or hide anything in the E-Mail.

The image itself has an almost entire lack of metadata at all (unless the software I'm using just isn't any good?) This means no location data tagged, nothing mentioning what camera / software was used to take the image, nothing. It's just a raw PNG with absolutely nothing added. Even Paint.net will tag a PNG with metadata saying that was the software used to save it. So I have to think the image had the metadata intentionally scrubbed (which isn't unusual for attachments that have gone through government e-mail).

One thing of possible minor interest is that the E-Mail was forwarded through slow1-d.mail.gandi.net, and gandi.net is a mail forwarder. Why would this have been necessary? (This is probably as simple as [email protected] has his mail hosted there.)

It appears that this is what happened: 1.) Ivan Cherkasov (London) sent the (original?) image to William Browder. Both at the "Hermitage Fund". (Does this mean this is a picture of her house in London?) 2.) William Browser forwarded it to Kyle Parker.
3.) Kyle Parker forwarded it to Robert Otto.

I don't know who any of these people are, obviously, but why were 4 people from all over the world interested in this woman's house if she was a "nobody" at the time?

There's definitely nothing additional added to the picture, and the pixels indicate that no steganography has been applied to the image itself. (Slim chance, I know, but I figured since reddit gets excited about it every time, I'd check.)
