</span>Okay. But there is no need to change anything in DK for storing thumbnails.<br>
The only thing needed is to change the way thumbnails are generated and<br>
updated for raw files.<br>
<br>
Simply, when DK finds a new raw file, instead of loading the embedded jpg file,<br>
simply call the raw processor and generate the new file. And when the thumbnail<br>
is dirty (as I explained before), regenerate the thumbnail.<br>
