I hate to sound like a picky person, but we nearly got severly burned on this, and I think we all need to remember this....
I see you have re-posetd pictures from our website, In this case it is OK for the images we have taken ourselves, but be forewarned, Some of the images (which we do not hold the rights to) are the property of others.
I know for a fact the collapsed station image is from our collection, as I personally touched up that image to remove some graffiti See the attachment
Just giving credit to your sourced 99% of the time will be enough gratification for the artist, and it is always polite to ask
Please use respect when 'borrowing' images from anywhere, as we have found even if you believe you have the rights to use them, often you actually do not, and are violating copyright laws that could lead to some financially stressful situations.
When in doubt just ask
