[Zope] IMG attributes in ZPT

[Troy Farrell]

Jon, I'm hear to second your request.  I got sick of the blatant XHTML 
standards violation here, so I edited Image.py, commenting out lines 748 
and 749.  Anyway, that fixes the direct call method.  I got sick of 
editing source code for all the installs (and to lazy to make a 
HotFix/Monkey Patch - religous debate anyone?), so for ZPT, I started 
using this when I didn't want to hard code it:

<img tal:define="image python:getattr(here.img,'guests_logo.png')"
      tal:attributes="src image/absolute_url;
                      height image/height;
                      width image/width;
                      alt image/title_or_id" style="border: 0;">

This works for an image guests_logo.png stored in a subfolder img.

HTH,
Troy

Specifically, I want to keep the WIDTH, HEIGHT, and ALT attributes as they render dynamically, but add a CLASS attribute, and get rid of the BORDER attribute.
