Message:

added a new option 'store_original_image'. If this is set, and the original image was converted to a new type, then we will also store the original. This was added for pei jones. Have tif images, want png source, thumb and screen images, but also want the tif files for doc editing purposes. have done no work on this if there are funny characters in the filename or different encodings
