Hey Wordies, I just added an 'image search' link under each word. It pipes the word you're on to Yahoo! image search and displays the first 8 results below the word (you can page through further images).
If you prefer to kick it old school you can get rid of this link. Click on 'you', then 'edit personal preferences, and you'll see radio buttons that let you set image search to automatic, on demand, or not there at all.
There's still some bugs to be worked out, in particular, you have to re-log in, and some punctuation makes it blow up. I'll work on these later today.
