Tricks for spotting a shortbox in photos?

[davepl]

Does anyone have any tricks for spotting a shotbox based on a photo? Since everyone tends to take front-corner photos like this:



I find it really hard to tell when there's only one photo and the depth of field is like that one above (which I assume is a standard long box). Plus no two people take their photos from the same distance and amount of zoom, so its hard to compare even to reference photos.

But if there's a tip on other clues that only shortboxes exhibit, it'd be handy to know! Like maybe the section between door and wheel is MUCH shorter on a shortbox, that sort of thing.

Thanks,
Dave
