[Seaside] Re: html images

[Frank Sukhu]

I am still trying to piece together how the machinery works but this tip
(see below)  from German has helped me.  As he suggested, I modified the
Form>asMIMEDocument to use a jpg type file instead of the default gif file;
this yielded better results.

Also, as others have mentioned, I probably have the depth to be an
inappropriate value.

What have I learned:

1. Using code like:  " html imageWithForm: (ImageReadWriter
formFromFileNamed: fn)." results in a gif file being served.  The gif file
has a default depth of 16.
2.  As mentioned (by David Shaffer in this thread), using option 1 is
wasteful.

Thanks for all the help,
Frank
