I agree that per-image flexibility is necessary.  But what if you wanted 
to have the same image resized in different places with different sizes? 
  I'm in favor of my earlier proposal of just specifing the height and 
width in the <img> tag.  Forrest, of course, would do the resizing, not 
the client.  This approach also brings the sizing close (from a code & 
file perspective) to the image reference, making it clearer.

This issue isn't a very high priority right now as most of us a busy 
with other things and the time we do have for Forrest is working on 
critical problems before we release 0.6.  Patches are certainly welcome 
:-)  At the least, we should add this as a feature request in the issue 
tracker (short title, summary links to this thread) so it isn't 
forgotten.  Since this is a new feature, we should start a new thread on 
dev@f.a.o to discuss actually implementing it.
