Sasha, as I know you're a connoisseur of 'tired woman' images to illustrate me/cfs ... the Guardian's article has an image of a woman on a bed (nice negligée!) which is credited to Getty Images.
Yes, I was thinking how like me she looked (give or take twenty years and the posh negligée, etc.)!
If you go to the Getty images site and look up cfs or chronic fatigue you don't get that image but if you search on "tired woman on bed" up it pops! Gawd knows what goes through the minds of newspaper picture editors when they're seeking illustrations, but I'm afraid "tired" is front and centre of their minds.
TBH, I think that "tired" is not a bad search term, and wouldn't be a bad search term for MS or similar diseases. The thing is, they're looking for search terms that will give them a pic of somebody lying down looking knackered and because photographers don't tag their images with "myalgic encephalomyelitis" or "multiple sclerosis", that's actually reasonable as one of the search terms.
The ones that I was forced to use, after much experimenting, were "depressed", "wheelchair", "bed" and so on. Like me, they may well be thinking of the image they need (someone lying in bed looking ill) and trying to think of the search term that will find such pix among the millions in the picture libraries.
