Stylesheet question

[JezB]

I want my imported stylesheets to completely control appearance, including
the images that appear on Image and ImageButton webcontrols. Can this be
done? I can only see an option to set the background-image, not the Image
itself.

I guess not, in the same way as stylesheets can't set the text on
webcontrols - I suppose this is "content" data, not just customizing
appearance.
