I also sent this photo to http://www.sungreen.co.uk/Coleford-Glos/Rising_Generation.html
They have a better copy sent in by another contributor - it is a postcard posted August 16th 1905, so it was obviously taken some time before then. They believe F N Jones was at 8 Gloucester Road, although he was certainly at No 12 when he took a photo of my Mother in 1921. And I believe he was operating from 8 St John St Coleford around the turn of the century (see the photo I posted of Joyford Baptist Chapel)
F N Jones married my Great Aunt Francis Matilda (VAUGHAN)b. abt 1869.
