Hi sparrowdown
I can hear the art direction now " yeah, totally pimp up the colours and make it look busier with extra car and foot traffic but sshh let's pretend the big-ass church isn't there." lol.
Actually I wonder how old the photograph is that WT has used considering the photo from Taichung, Taiwan they are currently using on the front page of the JW website, shown below, is using an old out-of-date tract / leaflet - I think they were replaced in 2013?
Google street view lets you go back and view older versions - the picture in Valparaíso, Chile that WT is using looks much more like the the Street View image from January 2012:
Admitedly the tarpaulin on the left looks a different color? But at least something is there. Likewise with the partial cover of the balcony in the middle. But the key item would seem to be the road sign on the right hand side, which doesn't appear in the latest Street View.
