Windows displays small to xlarge thumbnails/previews of jpg/gif/png/etc files as you browse directories in explorer and file open dialogs. Is there a way to get this to happen with gimp xcf files? Thanks for reading!
You'll have to make sure that entries are created in the Windows thumbnail caches (see http://en.wikipedia.org/wiki/Windows_thumbnail_cache). This could probably be done instead of or alongside the current thumbnail creation (which is using the Thumbnail Managing Standard, see http://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-late...)
This will require change to the GIMP source code.
