I'd like for files generated by a program I'm writing to show
bitmaps/previews in Explorer when in thumbnail view(like powerpoint,
visio, photoshop, etc. do)
Anyone know where to begin with this?

You need to create a thumbnail image handler, a COM object that
implements the IExtractImage interface and is registered with the file
type. See
