I would suggest you go to findagrave.com
I looked up the cemetery and here's what it is listed as on Findagrave:
Beckenham Cemetery and Crematorium
Also known as: Beckenham Crematorium & Cemetery, Elmers End Cemetery
Below is a link direct to this cemetery through findagrave.com. You can create a memorial for your family member and once that is done you can click on the button that says REQUEST A PHOTO. Volunteers in that area will go to that cemetery, find the grave and take a photo of it if there is a stone and then they will post it on the memorial you created. Make sure you set up your profile to notify you when a photo has been posted to your memorials. If you need help figuring out how to do this ... just send me all the information and I'll be happy to post it on your behalf. I've had lots of success here in the US getting photos of family stones all around the country.
