You shouldn't, the above should become a "Script (Python)":

r = context.REQUEST
r.setHeader('Content-Type', 'text/html;charset=utf-8')
r.set('img_url',context.images.absolute_url())
r.set('image_db_url', context.image_db.absolute_url())
context.session_init(context,REQUEST)

...now, I'd like to see the code for the session_init method since I'm pretty 
damn sure you don't need to be putting anything into the REQUEST bar the 
setHeader...

Eeep... hmm, well, as a start, you can get at it like:

<img href="" tal:attributes="href string:${request/img_url}/your_image_name.gif">

That said, I think I see what you're doing now, and you can probably, instead of 
your lump of dtml above do:

<html tal:define="dummy        python:request.RESPONSE.setHeader('Content-Type', 

                                                'text/html;charset=utf-8');
                   img_url      here/images/absolute_url;
                   image_db_url here/image_db/absolute_url;
                   dummy        here/session_init;">
<!-- whatever you want in here -->
</html>

cheers,

Chris
