Custom File Icons?

Hello,

Does anyone know how to create custom file icons from a Cocoa app?

I want to create miniature (preview) icons for graphic files created by my
application (like those created by Photoshop for example, that reflect the
actual content of the file as opposed to the apps normal document icon). BTW
these are not standard graphic formats like tiff or jpeg, rather they are
proprietary data files that lend themselves to visual representation.

I know how to create the source images. I know that I need to create ".icns"
files from my miniature images. I understand that these custom icons are
stored in an invisible file contained in each Finder folder. However, I have
no idea of how to associate them with my applications documents or how to
write them to that invisible file.

Of course I'm hoping there are some high-level Cocoa tools - but have not
been able to find anything... At any level.

Thanks,

-Darrel
