I judge "time to keg" by a couple of things- one is the beer being finished for at least three days and the next sign is the beer starting to clear.
It's hard to tell from the picture, but it looks like the beer is still pretty cloudy with yeast and floaties. I'd probably wait until it's reasonably clear before kegging it.
