So I looked into it... then I unblocked it.

So, what is s.ytimg.com?

Oh! It's a you tube domain!
$ nslookup s.ytimg.com Non-authoritative answer: s.ytimg.com canonical name = static.cache.l.google.com. Name: static.cache.l.google.com Address: 74.125.4.21
Yep, it really is, it's even got a canonical name in Google. Hmm... the name implies a cache, and the ‘yt' in ‘ytimg.com' is probably for You Tube, and if so the ‘img' probably stands for image.
A You Tube image cache? So it would seem.
A quick google URL search turns up lots of image tags that include it, I also found a couple of discussions:
Given that these references within the ytimg domain are probably being generated on the fly, I suspect that the code behind them is probably doing something with the cookies (including the obvious tracking).
So I have decided to unblock the whole ytimg.com domain, although in my case I have set the domain to "Allow for Session" in Firefox.

flash player on youtube
this just happened today...why is internet explorer not allowing me to see videos on youtube and gives this message:
"Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player."
when i go to download Adobe's Flash Player on ie, i get a runaround and am unable to get it.
on mozilla, everything is fine but i like ie quality of sound, much better than mozilla and more user friendly (in my opinion).

If on youtube right click on the time bar for video and you will see an area where you can allow or block s.ytimg.com from accessing your camera/mic
Interesting information
Interesting information there. I was on youtube and it suddenly tried to access my camera/microphone. Kind of creepy.
YouTube (s.ytimg.com) Video Camera Access
For those interested, I have a separate article on the attempted camera and microphone access that can happen on YouTube (and other Flash based sites).
See 'Stop YouTube (s.ytimg.com) Video Camera Spying' for more information.
Camera/microphone access?
A website that managed to attempt to access your camera/microphone!? You have got my attention.
Do you have any details?
it is adobe Flash player
it is adobe Flash player settings that allow camera and mic access. Right click the video display and select advanced, choose camera settings and you will see the choices.
