The source has the following clue:
<!-- read the whole url -->

The window title is:
'Look in the dark' = watch the picture closely (you may need to increase the brightness of your monitor.

Read the message that flashes up in the picture and apply its meaning by changing one word in the url.

I only just saw your post, so you've probably solved it by now (or found the answer elsewhere). I have just completed level 20 so can offer advice on anything up to there. To keep within the spirit of the game/puzzle I will only offer hints rather than reveal the solution on a public forum.
