[Seaside] serve jpg image files from form objects

[Martin Schubert]

hello out there,
allthough i browsed throught the archives i couldn`t find the answer  
to my problem.

i want to serve a jpg-file which is stored in a Form object.
so i do : aForm _ (Form fromFileNamed: 'wave.jpg')

then i tried the following inside the #renderContentOn:  method :
	
html imageWithDocument: aForm bits asByteArray
		mimeType: 'image/jpeg'
		fileName: root name,'Picture', '.jpg'.

this doesn`t work, and when i am acceptin the following, seaside  
seems to convert the jpg file to gif or wracks up the picture file  
somehow :

	html imageWithDocument: aForm
		mimeType: 'image/jpeg'
		fileName: root name,'Picture', '.jpg'.

anybodys having some experience with this issue?
thanks for help!
