Alternatives to System.Drawing for use with ASP.NE

Question

After several days of tracking down bizarre GDI+ errors, I've stumbled across this little gem on MSDN:

Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.

I don't know whether "ASP.NET service" means "web application" in this context, but "diminished service performance" certainly seems to cover the random assortment of "A generic error occurred in GDI+" and "Out of memory" errors that my app is throwing - intermittent, non-reproducible errors reading and writing JPEG images that - in many cases - were actually created by System.Drawing.Imaging in the first place.

So - if GDI+ can't read and write JPEG files reliably in a Web app, what should I be using instead?

I want users to be able to upload images (JPEG required, other formats nice-to-have), resample them reliably, and display useful error messages if anything goes wrong. Any ideas? Are the System.Media namespaces from WPF worth considering?

EDIT: Yeah, I know GDI+ works "most of the time". That's not good enough, because when it fails, it does so in a way that's impossible to isolate or recover from gracefully. I am not interested in examples of GDI+ code that works for you: I am looking for alternative libraries to use for image processing.

You may have a look at http://gd-sharp.sourceforge.net/ which is a wrapper for the GD library. I haven't tested it but it seems promising.
