Why don't you use a layout like
/
   /folder_800
   /folder_1024
   /content

And just acquire content in the right position
i.e. folder_800/content/blabla => 800 optimized
and folder_1024/content/blabla => 1024 optimzed

where blabla's physical location is /content/blabla

Now give folder_800, folder_1024 and content a int property, say "res".
Then you only need javscript in your start page, the rest can be constructed
solely in zope, without javascript, like <img src='fdf' width=<dtml-var 
"res/100">>.
Additionally you can use the content folder for browsers without javascript.
