Maybe I am not clear. What I want is something like this:

Bla Bla <img src=whatever.jpg width=50%/> bla bla.

being the same as

Bla Bla <img src=whatever.jpg width=100/> bla bla.

in a frame that's 200pt wide. 

As I said, I have it working for images as a separate flowable, it's just with 
images inline on paragraph xml markup that I can't figure it out.
