Updated for 1.9.50.
Didn't test it but should be fine... Tell me how it works.
By the way, as Znuffie suggested, it might be interesting to use Jabber as remote server.
Advantages:
- does not depend on any remote server storing your data
- faster (BOSH > AJAX)
- allow remote access to the bot even if you're behind a firewall
- very easy to set up: create a jabber account on a server (ex. jabber.org, takes 30 seconds), set its user/passwd infos in cowstats, and you're ready to rock.
Cons:
- takes a bit of time to implement
- I'm not even sure people are using the current version and would use that new feature
- I actually got 2 "thanks" and 5 dollars (thank you very much, you'll recognise yourself

)
=> If you'd like to see that wonderful feature, might be great to tell me what you think about it.
Note:
Jabber = XMPP protocol, which is used on facebook's chat and gmail's too, for example. And yes, it WILL support live screenshots. I did some tests about this and you can display a binary picture without hosting it somewhere.
