Yes, you're right. I've added a ``nohints'' attribute to navbar:render,
the http://www.engelschall.com/sw/wml/test/gimp shows the result.

Thanks for the explanations.
I think you should not mix button definition and image generation. 
You may define a tag to build your pictures, with the ``imgstyle''
attribute. Take a look at <wml::des::gfont>, it provides a ``notag''
attribute for writing images without generating <img> tag.

It's easier to debug and maintain. And in your template you can define
your own macros to generate image files and appropriate navbar
definitions.
