[Seaside] Serving on the fly MIMEDocument

[Sebastian Sastre]

Hi there,

	I'm generating an image dynamically and I can't figure out how to serve
it. I've tried:

	html image
		document: aMIMEDocument
		mimeType: aMIMEDocument mimeType
		yourself.

	with no success. Should I write to disk and serve from there or there is
a way to serve it on the fly?

	thanks,

Sebastian 
PS: that MIMEDocument has its contents (is a gif)
