[Seaside] Problem showing a JPEG to the world

[seaside at fbeausoleil.ftml.net]

Hi !

I'm having a problem putting a picture out.  I'm doing this in my 
renderContentOn:

   html imageWithForm: ((pict picture) scaledToSize: 220 at 165).

imageWithForm: renders the image as a GIF, using the web palette.  The 
original image is a JPEG, and I would like to output it as such.

Where have I gone wrong ?  I'm a relative newbie to Squeak and Seaside, 
but I like them both  :)   You'll get a convert real-soon-now...

Thanks !
François
