These particular images I have found through a book recently published by Boydell and Brewer, Medieval Wall Painting. There are many more examples in here that I would quite like to show, and perhaps we will in the near future -- provided I can find images online.
As that is extremely time consuming, for the moment I will share these images I found and put together last week.

St. Clement, Ashampstead
An image that I cannot post here due to copyright, but which should be viewed is found in Ashampstead, in the parish of St. Clement and depicts the Nativity. Do take note of the detail and imagine it as it would have been originally.
