Firstly, all the images are almost exactly the same scale. If you know what one city is, you can compare other ones to it and get a rough estimate of whether they're larger or smaller.
Depending on how much time you've spent on JetPunk, you're probably familiar 80-95% of the cities shown. There's a couple obscure ones, but most of them are pretty well-known.
In general, the clearer, sharper satellite photos are from richer countries and areas. There are exceptions to this, of course, but it might be a good way to narrow down your search.
Finally, most of the cities are pretty much centred in the frame. If you have an image of a city that isn't centred, it's probably because the stuff on the other side of the photo is a potential clue—pay attention to it!
