I think I can understand why the gunzels find this irritating. All media outlets do this kind of thing from time to time — I’m only using an image from the Herald Sun here because they happen this morning to be showing two on the same page.
They have a story, say, something about trains, so they grab the first image from their library that matches the right keywords, and use it, without checking if it’s from the right city.
In this case, it appears the Doncaster line story is illustrated by a Sydney double-decker train (I’m no expert but it appears to be one of the new Millennium fleet), and the Seaford level crossing accident is illustrated by an Adelaide train at a level crossing — I recognise the Adelaide colour scheme, which is used on trains, trams and buses there. (It is a Comeng though.)
The Metro performance story is illustrated by the correct type of train and platform staff member. The picture may be a few months old, as most (but not all) of the Comeng fleet have now been done over in the new Metro colour scheme.
Perhaps one out of three ain’t bad.
It happens in other industries too. Those who work in IT will know that recruiters looking for people will try to fill jobs by looking for someone with a CV that matches some (but sometimes not all) of the keywords on the job description they’ve been handed by the employer… years ago I remember being asked if skill X1 was related to skill X2, because I had X1 but not the desired X2… alas, the skills were unrelated, or certainly not directly transferable.
