Douglas was a private in the Green Howards (Yorkshire Regiment) 6th Bn. He is buried locally (to me) in the Walkley (St. Mary) Church Cemetery, Sheffield, England. So I will get you a photograph. I hope you can see my email address to contact me, if not go on my website http://www.stannington.webitsmart.co.uk/http://www.stannington.webitsmart.co.uk/
choose 'contact me' option and I'll be able to email you back.
I can also send you a picture of the Stannington War memorial which they will be remembered on.
