This is an issue that I am also going to have to deal with as I try to
migrate my OOo manuals to Forrest. I can link to an image file, which OOo
can scale to suit me, but the chances are that the image size will be wrong
if the same image file is referenced in a Forrest document. You might want a
smaller image in the HTML, but still want to be able to view the image at
the full resoution (think: screen shots).

Now, if images could be referenced using the site: mechanism as hrefs  (<img
src="site:images/screenshot">), then you could control how images were
rendered with something like this (in site.xml):

<images href="full-size-images/">
    <screenshot href="ss1.bmp" width="100" height="60" expand="Click to view
this screen shot full-size"/>

The height and width attributes limit the size when viewed in the main page
(simply pass the attributes through to the HTML <img> tag which will allow
the browser to do the scaling), and if the expand attribute is present then
render the image something like this:

<a href="full-size-images/screenshot.html">
   <img src="full-size-images/ss1.bmp" width="100" height="60"
   alt="Click to view this screen shot full-size" />

No doubt a few details missing but you get the idea. What do you think?
