EXIF Thumbnails

Working with the pyexiv2 library, discovered that images from digital camera’s typically have an embedded thumbnail image, available via standard metadata (EXIF) that is included within the image itself. Work with thumbnail images generated by the camera is interestesting in that it helps speed the process of working with the bulk of images (no need to regenerate the thumbnail) and somehow honoring the actual data in that the thumbnail had been generated by the specific camera.
