Mark & all,

Great example! It is now slightly modified for the OPS XForms engine,
and running online (no install required, it's Ajax-based, and works
with IE and Mozilla/Firefox):

   http://www.orbeon.com/ops/goto-example/xforms-flickr-resize

Besides converting from HTML to XHTML, we had to make these changes:

o Updated XPath expression to use XPath 2.0 if() (if only the XForms
   Working Group had *not* named its function "if").

o OPS does not as of yet support the xforms\:something notation in
   CSS, but uses classes of the form .xforms-something.

Minor changes, mainly for usability / appearance:

o Put default "flower" value as tags.

o Set minimum slider value to 10 instead of 1.

o More explicit labels, some descriptive text, and updates to layout
   and style.

o Submission can be done also by pressing "enter" in the input field
   (DOMActivate runs xforms:send).

o Added xforms:output to display the current value of the slider, as
   the OPS slider does not show the numerical value.

o Put hidden <span> in repeat so that IE flows the images correctly.

The resulting source code is here:

   http://www.orbeon.com/ops/goto-source/xforms-flickr-resize/view.xhtml

Enjoy,

-Erik

PS : Note that I am not sure about the license of the initial source
code: we just followed the tutorial and made changes. For now I put a
note saying that the code was written following your tutorial, but let
me know, Mark, what's the proper way of giving credit.
