Did I miss some recent website updates?
I just ran into 孫權, and the definition now has a picture included in it.

Now, it would you be nice if we could click and see it in larger size, because it's kind of small right now, and I can't really tell what 孫權 looks like ;)

We're putting them in as the standard definitions just for a few famous people, for now. Later we're thinking of making a much better picture mode, where Skritter hosts the images in different sizes, and then we'll have an option to either have pictures in definitions turned on or off, and each word will aspire to having its own picture.

You can always edit your own definitions to have pictures by putting img:http://www.example.com/some_picture.jpg in the custom definition. Skritter will scale it down to 75px tall for right now.

It seems that some words will be easier to get pictures for than others!

Should be interesting watching this develop though, I'm all for it!
