GDI/reading image dimensions

Hi all,

I'm in search of a fast solution to reading image dimensions. I know
you can get the image dimensions by loading a file into an image
object, and then reading the height/width properties, but this is
really slow (relatively speaking).

Another poster suggested I could read the image headers manually by
streaming the first X number of bytes of the file, but this is fairly
consuming approach and hoping there's another option.

United Binary's AutoImageInfo (that has a .NET wrapper) works great,
and runs on my box in about 20ms on fairly large file.

Any ideas for components or methods to handle this?

Thanks,
Tom
