YouTube videos have black bars.

The solution to this is http://i1.ytimg.com/vi/ID/maxresdefault.jpg, however this seems to work arbitrarily, not returning anything in some cases. The "mqdefault.jpg" seems to be the only one without the black bars, but isn't very high res.

I've attached a simple table which compares the different thumbnails. mqdefault and maxresdefault are the only two that do not include black bars. maxresdefault also is not reliable, sometimes appearing, sometimes not. The issue with mqdefault is that it only appears at, 320x180, which is quite low resolution.

Possible solutions:

• Only deal with smaller thumbs.
• Allow some of the thumbs not to work.
• Attempt to grab the high res thumb, then fall back to the smaller one.

I couldn't see how, in this version of guzzle, to just get the headers instead of downloading the whole response.

In my test here are two of the thumbnails downloaded. One at the smaller size (where a large was not available) and one at the large size. Neither have black bars.

There it is, example in install_check_localization_server. Doesn't hint for some reason.

Also, like this implementation better.
