If he is buried in that cemetery, the Sons of Confederate Veterans, specifically Robert Edwards from teh David O. Dodd Camp in Benton, Arkansas has high resolution digital photos of every Confederate grave in that cemetery and I am sure he would have that picture as well. He is working on a very large database. You can go to arkansasscv.org and track him down under the Division Officers tab at the top. This cemetery is very interesting as the local UDC placed their own Confederate Iron Crosses on the graves of Confederates there.
