Unfortunately, the Navigation Services custom preview feature is
limited to previews drawn within the client application. There is no
plug-in architecture for a client to provide previews to all
applications. On the other hand, NSOpen/Save, Finder and Nav
currently (Tiger) use ImageIO to present their image previews.
Perhaps CG has a mechanism to provide custom image previews for all
ImageIO clients?

Hi,
NSOpenPanel, the Finder, and Navigation Services all show previews for
files, at least when in column view. This works especially well
for images.
Is it possible to write some kind of plugin so that the OS can also
show
a preview for my custom image format?
From what I can tell, only Nav Serv supports this:

Is it possible for NSOpenPanel and the Finder too?
Thanks!
