Strangely, Adobe's website lists GIMP as supporting DNG (read-only): http://www.adobe.com/products/dng/supporters.html AFAIK there isn't _any_ specific support for it. It should be possible to hack something based on the TIFF plug-in, as DNG is based on TIFF. TIFF/EP actually. In fact that's why the TIFF plug-in opens the thumbnail image in the DNG file. Quote: "Therefore, if the full-resolution image is stored using compression, the TIFF/EP file should include a thumbnail image stored in the 0th IFD that is readable by a baseline TIFF 6.0 reader. This thumbnail should not be compressed, and should be stored in strips, rather than in tiles, in order to be fully compatible with TIFF 6.0. A SubIFDs tag in the 0th IFD is used to point to the compressed full-resolution image. If the full-resolution image is stored uncompressed as a baseline-readable TIFF image, the full-resolution image could be stored in the 0th IFD. However, TIFF/EP recommends that a thumbnail image be stored in the 0th IFD, regardless of whether the full-resolution image is baseline TIFF readable or not. This provides a version of the image that is small (relative to the full-resolution image) and that may be quickly accessed by reader software."
