Seaside doesn't expect to serve static content itself - it expects to
either be behind apache, or perhaps to have Comanche configured to serve
from a directory on a different port.  Either way, the url for content
like images will not be relative to your Seaside application, it will be
something like http://yourhost/seaside-images/image.jpg.

So you have two choices - for a known src, you can just put a plain image
tag as you did above, but with an absolute url.  For a dynamic src, you
can do something like

<img src="@imageName">

which will by default bind the #src attribute to the value of the
#imageName method.  This is where the document root comes in - Seaside
prepends the url given as document root to the value of #src.

So, if you had

imageName
  ^ 'image.jpg'

and

<img src="@imageName">

and document root was set to http://yourhost/seaside-images,

you would get <img src="http://yourhost/seaside-images/image.jpg">.

Now, maybe there should be a way to serve images from within Seaside
without setting up a separate server for static content, but this has
worked out for me so far.

This all make sense?
