Beer, I am speechless and in awe of everyone's kindness. I only posted this request about 10 hours ago, and already the probability of getting the photo has increased from "absolute zero" to "possible".

I followed the link that gargoyle posted to another site which lists the graves. This site says Grave 22 and not Grave 23. I am more inclined to believe the scanned copy of the original letter, but this was typed too and either of the records could have a typo. But the rest of the information is the same so the grave will either be 22 or 23.

This site has information about Pozières Cemetery

and there is even a plan of the cemetery

Click on the plan to increase the size to make it readable.

The grave of my great uncle would be on the lower right hand side of the plan, I think.

Immeasurable thanks, everyone, for your help, ideas and enthusiasm for what I thought would be a long shot request.
