Thread:Project:Support desk/Dynamic header image

Although it seems to be poorly documented on this site, most MW skins allow you to specify a banner image as the background for the header. However, what if you (like me) want to be able to choose different header images on a per-page/per-template basis? If, for instance, you have a website about bicycles, cars and helicopters, it would make good sense to have a number of thematic variations on the default header image. The change of image would then be triggered by a template used on the page.

Would it be somehow possible to do this? Or does anyone have alternative ideas? The only alternative I can think of is to change the logo (rather then the header) on a per-page basis using Extension:Logotipo.
